MusicBrainz is a project that aims to create an open data music database, similar to the freedb project. MusicBrainz was founded in response to the restrictions placed on the Compact Disc Database, a database for software applications to look up audio CD information on the Internet. MusicBrainz has expanded its goals to reach beyond a compact disc metadata storehouse to become a structured open online database for music. MusicBrainz captures information about artists, their recorded works, the relationships between them. Recorded works entries capture at a minimum the album title, track titles, the length of each track; these entries are maintained by volunteer editors. Recorded works can store information about the release date and country, the CD ID, cover art, acoustic fingerprint, free-form annotation text and other metadata; as of 21 September 2018, MusicBrainz contained information about 1.4 million artists, 2 million releases, 19 million recordings. End-users can use software that communicates with MusicBrainz to add metadata tags to their digital media files, such as FLAC, MP3, Ogg Vorbis or AAC.
MusicBrainz allows contributors to upload cover art images of releases to the database. Internet Archive provides the bandwidth and legal protection for hosting the images, while MusicBrainz stores metadata and provides public access through the web and via an API for third parties to use; as with other contributions, the MusicBrainz community is in charge of maintaining and reviewing the data. Cover art is provided for items on sale at Amazon.com and some other online resources, but CAA is now preferred because it gives the community more control and flexibility for managing the images. Besides collecting metadata about music, MusicBrainz allows looking up recordings by their acoustic fingerprint. A separate application, such as MusicBrainz Picard, must be used for this. In 2000, MusicBrainz started using Relatable's patented TRM for acoustic fingerprint matching; this feature allowed the database to grow quickly. However, by 2005 TRM was showing scalability issues as the number of tracks in the database had reached into the millions.
This issue was resolved in May 2006 when MusicBrainz partnered with MusicIP, replacing TRM with MusicDNS. TRMs were phased out and replaced by MusicDNS in November 2008. In October 2009 MusicIP was acquired by AmpliFIND; some time after the acquisition, the MusicDNS service began having intermittent problems. Since the future of the free identification service was uncertain, a replacement for it was sought; the Chromaprint acoustic fingerprinting algorithm, the basis for AcoustID identification service, was started in February 2010 by a long-time MusicBrainz contributor Lukáš Lalinský. While AcoustID and Chromaprint are not MusicBrainz projects, they are tied with each other and both are open source. Chromaprint works by analyzing the first two minutes of a track, detecting the strength in each of 12 pitch classes, storing these 8 times per second. Additional post-processing is applied to compress this fingerprint while retaining patterns; the AcoustID search server searches from the database of fingerprints by similarity and returns the AcoustID identifier along with MusicBrainz recording identifiers if known.
Since 2003, MusicBrainz's core data are in the public domain, additional content, including moderation data, is placed under the Creative Commons CC-BY-NC-SA-2.0 license. The relational database management system is PostgreSQL; the server software is covered by the GNU General Public License. The MusicBrainz client software library, libmusicbrainz, is licensed under the GNU Lesser General Public License, which allows use of the code by proprietary software products. In December 2004, the MusicBrainz project was turned over to the MetaBrainz Foundation, a non-profit group, by its creator Robert Kaye. On 20 January 2006, the first commercial venture to use MusicBrainz data was the Barcelona, Spain-based Linkara in their Linkara Música service. On 28 June 2007, BBC announced that it has licensed MusicBrainz's live data feed to augment their music Web pages; the BBC online music editors will join the MusicBrainz community to contribute their knowledge to the database. On 28 July 2008, the beta of the new BBC Music site was launched, which publishes a page for each MusicBrainz artist.

An electric guitar is a guitar that uses one or more pickups to convert the vibration of its strings into electrical signals. The vibration occurs when a guitar player strums, fingerpicks, slaps or taps the strings; the pickup uses electromagnetic induction to create this signal, which being weak is fed into a guitar amplifier before being sent to the speaker, which converts it into audible sound. The electric signal can be electronically altered to change the timbre of the sound; the signal is modified using effects such as reverb, distortion and "overdrive". Invented in 1931, the electric guitar was adopted by jazz guitar players, who wanted to play single-note guitar solos in large big band ensembles. Early proponents of the electric guitar on record include Les Paul, Lonnie Johnson, Sister Rosetta Tharpe, T-Bone Walker, Charlie Christian. During the 1950s and 1960s, the electric guitar became the most important instrument in popular music, it has evolved into an instrument, capable of a multitude of sounds and styles in genres ranging from pop and rock to country music and jazz.
It served as a major component in the development of electric blues and roll, rock music, heavy metal music and many other genres of music. Electric guitar design and construction varies in the shape of the body and the configuration of the neck and pickups. Guitars may have a fixed bridge or a spring-loaded hinged bridge, which lets players "bend" the pitch of notes or chords up or down, or perform vibrato effects; the sound of an electric guitar can be modified by new playing techniques such as string bending and hammering-on, using audio feedback, or slide guitar playing. There are several types of electric guitar, including: the solid-body guitar. In pop and rock music, the electric guitar is used in two roles: as a rhythm guitar, which plays the chord sequences or progressions, riffs, sets the beat. In a small group, such as a power trio, one guitarist switches between both roles. In large rock and metal bands, there is a rhythm guitarist and a lead guitarist. Many experiments at electrically amplifying the vibrations of a string instrument were made dating back to the early part of the 20th century.
Patents from the 1910s show telephone transmitters were adapted and placed inside violins and banjos to amplify the sound. Hobbyists in the 1920s used carbon button microphones attached to the bridge. With numerous people experimenting with electrical instruments in the 1920s and early 1930s, there are many claimants to have been the first to invent an electric guitar. Electric guitars were designed by acoustic guitar makers and instrument manufacturers; the demand for amplified guitars began during the big band era. The first electric guitars used in jazz were hollow archtop acoustic guitar bodies with electromagnetic transducers. Early electric guitar manufacturers include Rickenbacker in 1932; the first electrically amplified stringed instrument to be marketed commercially was designed in 1931 by George Beauchamp, the general manager of the National Guitar Corporation, with Paul Barth, vice president. The maple body prototype for the one-piece cast aluminium "frying pan" was built by Harry Watson, factory superintendent of the National Guitar Corporation.
Commercial production began in late summer of 1932 by the Ro-Pat-In Corporation, in Los Angeles, a partnership of Beauchamp, Adolph Rickenbacker, Paul Barth. In 1934, the company was renamed the Rickenbacker Electro Stringed Instrument Company. In that year Beauchamp applied for a United States patent for an Electrical Stringed Musical Instrument and the patent was issued in 1937. By early-mid 1935, Electro String Instrument Corporation had achieved mainstream success with the A-22 "Frying Pan" steel guitar, set out to capture a new audience through its release of the Electro-Spanish Model B and the Electro-Spanish Ken Roberts, the first full 25" scale electric guitar produced; the Electro-Spanish Ken Roberts was revolutionary for its time, providing players a full 25" scale, with easy access to 17 frets free of the body. Unlike other lap-steel electrified instruments produced during the time, the Electro-Spanish Ken Roberts was designed to play standing vertical, upright with a strap; the Electro-Spanish Ken Roberts was the first instrument to feature a hand-operated vibrato as a standard appointment, a device called the "Vibrola," invented by Doc Kauffman.
It is estimated that fewer than 50 Electro-Spanish Ken Roberts were constructed between 1933 and 1937. The solid-body electric guitar is made without functionally resonating air spaces; the first solid-body Spanish standard guitar was offered by Vivi-Tone no than 1934. This model featured a guitar-shaped body of a single sheet
A drum kit — called a drum set, trap set, or drums — is a collection of drums and other percussion instruments cymbals, which are set up on stands to be played by a single player, with drumsticks held in both hands, the feet operating pedals that control the hi-hat cymbal and the beater for the bass drum. A drum kit consists of a mix of drums and idiophones – most cymbals, but can include the woodblock and cowbell. In the 2000s, some kits include electronic instruments. Both hybrid and electronic kits are used. A standard modern kit, as used in popular music and taught in music schools, contains: A snare drum, mounted on a stand, placed between the player's knees and played with drum sticks A bass drum, played by a pedal operated by the right foot, which moves a felt-covered beater One or more toms, played with sticks or brushes A hi-hat, played with the sticks and closed with left foot pedal One or more cymbals, mounted on stands, played with the sticksAll of these are classified as non-pitched percussion, allowing the music to be scored using percussion notation, for which a loose semi-standardized form exists for both the drum kit and electronic drums.
The drum kit is played while seated on a stool known as a throne. While many instruments like the guitar or piano are capable of performing melodies and chords, most drum kits are unable to achieve this as they produce sounds of indeterminate pitch; the drum kit is a part of the standard rhythm section, used in many types of popular and traditional music styles, ranging from rock and pop to blues and jazz. Other standard instruments used in the rhythm section include the piano, electric guitar, electric bass, keyboards. Many drummers extend their kits from this basic configuration, adding more drums, more cymbals, many other instruments including pitched percussion. In some styles of music, particular extensions are normal. For example, some rock and heavy metal drummers make use of double bass drums, which can be achieved with either a second bass drum or a remote double foot pedal; some progressive drummers may include orchestral percussion such as gongs and tubular bells in their rig. Some performers, such as some rockabilly drummers, play small kits that omit elements from the basic setup.
Before the development of the drum set and cymbals used in military and orchestral music settings were played separately by different percussionists. In the 1840s, percussionists began to experiment with foot pedals as a way to enable them to play more than one instrument, but these devices would not be mass-produced for another 75 years. By the 1860s, percussionists started combining multiple drums into a set; the bass drum, snare drum and other percussion instruments were all struck with hand-held drum sticks. Drummers in musical theater shows and stage shows, where the budget for pit orchestras was limited, contributed to the creation of the drum set by developing techniques and devices that would enable them to cover the roles of multiple percussionists. Double-drumming was developed to enable one person to play the bass and snare with sticks, while the cymbals could be played by tapping the foot on a "low-boy". With this approach, the bass drum was played on beats one and three. While the music was first designed to accompany marching soldiers, this simple and straightforward drumming approach led to the birth of ragtime music when the simplistic marching beats became more syncopated.
This resulted in dance feel. The drum set was referred to as a "trap set", from the late 1800s to the 1930s, drummers were referred to as "trap drummers". By the 1870s, drummers were using an "overhang pedal". Most drummers in the 1870s preferred to do double drumming without any pedal to play multiple drums, rather than use an overhang pedal. Companies patented their pedal systems such as Dee Dee Chandler of New Orleans 1904–05. Liberating the hands for the first time, this evolution saw the bass drum played with the foot of a standing percussionist; the bass drum became the central piece around which every other percussion instrument would revolve. William F. Ludwig, Sr. and his brother, Theobald Ludwig, founded the Ludwig & Ludwig Co. in 1909 and patented the first commercially successful bass drum pedal system, paving the way for the modern drum kit. Wire brushes for use with drums and cymbals were introduced in 1912; the need for brushes arose due to the problem of the drum sound overshadowing the other instruments on stage.
Drummers began using metal fly swatters to reduce the volume on stage next to the other acoustic instruments. Drummers could still play the rudimentary snare figures and grooves with brushes that they would play with drumsticks. By World War I, drum kits were marching band-style military bass drums with many percussion items suspended on and around them. Drum kits became a central part of jazz Dixieland; the modern drum kit was developed in the vaudeville era during the 1920s in New Orleans. In 1917, a New Orleans band called "The Original Dixieland Jazz Band " recorded jazz tunes that became hits all o
Singing is the act of producing musical sounds with the voice and augments regular speech by the use of sustained tonality, a variety of vocal techniques. A person who sings is called a vocalist. Singers perform music that can be sung without accompaniment by musical instruments. Singing is done in an ensemble of musicians, such as a choir of singers or a band of instrumentalists. Singers may perform as soloists or accompanied by anything from a single instrument up to a symphony orchestra or big band. Different singing styles include art music such as opera and Chinese opera, Indian music and religious music styles such as gospel, traditional music styles, world music, blues and popular music styles such as pop, electronic dance music and filmi. Singing arranged or improvised, it may be done as a form of religious devotion, as a hobby, as a source of pleasure, comfort or ritual, as part of music education or as a profession. Excellence in singing requires time, dedication and regular practice.
If practice is done on a regular basis the sounds can become more clear and strong. Professional singers build their careers around one specific musical genre, such as classical or rock, although there are singers with crossover success, they take voice training provided by voice teachers or vocal coaches throughout their careers. In its physical aspect, singing has a well-defined technique that depends on the use of the lungs, which act as an air supply or bellows. Though these four mechanisms function independently, they are coordinated in the establishment of a vocal technique and are made to interact upon one another. During passive breathing, air is inhaled with the diaphragm while exhalation occurs without any effort. Exhalation may be aided by lower pelvis/pelvic muscles. Inhalation is aided by use of external intercostals and sternocleidomastoid muscles; the pitch is altered with the vocal cords. With the lips closed, this is called humming; the sound of each individual's singing voice is unique not only because of the actual shape and size of an individual's vocal cords but due to the size and shape of the rest of that person's body.
Humans have vocal folds which can loosen, tighten, or change their thickness, over which breath can be transferred at varying pressures. The shape of the chest and neck, the position of the tongue, the tightness of otherwise unrelated muscles can be altered. Any one of these actions results in a change in pitch, timbre, or tone of the sound produced. Sound resonates within different parts of the body and an individual's size and bone structure can affect the sound produced by an individual. Singers can learn to project sound in certain ways so that it resonates better within their vocal tract; this is known as vocal resonation. Another major influence on vocal sound and production is the function of the larynx which people can manipulate in different ways to produce different sounds; these different kinds of laryngeal function are described as different kinds of vocal registers. The primary method for singers to accomplish this is through the use of the Singer's Formant, it has been shown that a more powerful voice may be achieved with a fatter and fluid-like vocal fold mucosa.
The more pliable the mucosa, the more efficient the transfer of energy from the airflow to the vocal folds. Vocal registration refers to the system of vocal registers within the voice. A register in the voice is a particular series of tones, produced in the same vibratory pattern of the vocal folds, possessing the same quality. Registers originate in laryngeal function, they occur. Each of these vibratory patterns appears within a particular range of pitches and produces certain characteristic sounds; the occurrence of registers has been attributed to effects of the acoustic interaction between the vocal fold oscillation and the vocal tract. The term "register" can be somewhat confusing; the term register can be used to refer to any of the following: A particular part of the vocal range such as the upper, middle, or lower registers. A resonance area such as chest voice or head voice. A phonatory process A certain vocal timbre or vocal "color" A region of the voice, defined or delimited by vocal breaks.
In linguistics, a register language is a language which combines tone and vowel phonation into a single phonological system. Within speech pathology, the term vocal register has three constituent elements: a certain vibratory pattern of the vocal folds, a certain series of pitches, a certain type of sound. Speech pathologists identify four vocal registers based on the physiology of laryngeal function: the vocal fry register, the modal register, the falsetto register, the whistle register; this view is adopted by many vocal pedagogues. Vocal resonation is the process by which the basic product of phonation is en
Doom metal is an extreme subgenre of heavy metal music that uses slower tempos, low-tuned guitars and a much "thicker" or "heavier" sound than other heavy metal genres. Both the music and the lyrics intend to evoke a sense of despair and impending doom; the genre is influenced by the early work of Black Sabbath, who formed a prototype for doom metal with songs such as "Black Sabbath", "Children of the Grave", "Electric Funeral" and "Into the Void". During the first half of the 1980s, a number of bands from England, the United States and Sweden defined doom metal as a distinct genre; the electric guitar, bass guitar and drum kit are the most common instruments used to play doom metal, but its structures are rooted in the same scales as in blues. Guitarists and bassists downtune their instruments to low notes and make use of large amounts of distortion, thus producing a "thick" or "heavy" guitar tone, one of the defining characteristics of the genre. Along with the usual heavy metal compositional technique of guitars and bass playing the same riff in unison, this creates an impressively loud and bass-heavy wall of sound.
Another defining characteristic is the consistent focus on slow tempos, minor tonality with much use of dissonance. Traditional doom metal vocalists favour clean vocals, which are performed with a sense of despair, desperation or pain. So-called "epic doom" vocalists take it a step further, singing in an operatic style. Doom metal bands influenced by other extreme metal genres use growled or screamed vocals, as is the case of death-doom, black-doom, funeral doom. Lyrics in doom metal play a key role. Influenced by notable blues musicians like Robert Johnson and Son House they are gloomy and pessimistic, including themes such as: suffering, fear, dread and anger. While some bands write lyrics in introspective and personal ways, others convey their themes using symbolism – which may be inspired by occult arts and literature; some doom metal bands use religious themes in their music. Trouble, one of the genre's pioneers, were among the first to incorporate Christian imagery. Others have incorporated pagan imagery.
For many bands, the use of religious themes is for symbolic purposes only. Examples include lyrics/imagery about the Last Judgment to invoke dread, or the use of crucifixes and cross-shaped headstones to symbolize death. Furthermore, some doom metal bands write lyrics about drugs or drug addiction; this is most common among stoner doom bands, who describe hallucinogenic or psychedelic experiences. Doom metal is rooted in the music of early Black Sabbath. Black Sabbath's music is itself stylistically rooted in blues, but with the deliberately doomy and loud guitar playing of Tony Iommi, the then-uncommon dark and pessimistic lyrics and atmosphere, they set the standards of early heavy metal and inspired various doom metal bands. In the early 1970s both Black Sabbath and Pentagram composed and performed this heavy and dark music, which would in the 1980s begin to be known and referred to as doom metal by subsequent musicians and fans. Aside from Pentagram and Black Sabbath, other groups from the 70s would influence the genre's development.
Blue Cheer is hailed as one of the first stoner metal bands. Through the use of loud amplifiers and guitar feedback, their debut Vincebus Eruptum created a template for other artists to follow. Though lacking the pessimistic lyrical content of their contemporaries, Welsh heavy metal band Budgie would produce heavy songs which were amongst the loudest of their day, stylistically influencing various doom metal acts. Early doom metal was influenced by Japan's Flower Travellin' Band their albums Kirikyogen and Satori. Other notable groups include Sir Lord Baltimore, Bang, Lucifer's Friend, Iron Claw and Leaf Hound. During the early-mid-1980s, bands from England and the United States contributed much to the formation of doom metal as a distinct genre. In 1982, English pioneers Witchfinder General released their debut album Death Penalty. During 1984 and 1985, three American pioneers released their debuts; the Swedish Candlemass would prove influential with their first record Epicus Doomicus Metallicus in 1986, from which the genre takes its name.
Some doom metal bands were influenced by the underground gothic rock and post-punk scene of the 1980s, showing similarities with the dark themes addressed through lyrics and the music atmosphere, both music styles deal with. A doom metal band like Mindrot was described as a cross-over between death metal and gothic rock. Like other extreme metal genres, doom metal has regionally based scenes, with their own particular characteristics: In one of the greatest doom metal outputs, Finnish groups focus more on the depressive mood of the genre, evoking an intense grieving feeling; the bands play with slow tempos and melodic tones, creating an atmosphere of darkness and melancholia. This scene was kick-started by the band Rigor Mortis, which originated in 1987. Notable bands include Reverend Bizarre, Dolorian, Shape of Despair, Skeptici
Henry Wadsworth Longfellow
Henry Wadsworth Longfellow was an American poet and educator whose works include "Paul Revere's Ride", The Song of Hiawatha, Evangeline. He was the first American to translate Dante Alighieri's Divine Comedy and was one of the Fireside Poets from New England. Longfellow was born in Portland, still part of Massachusetts, he studied at Bowdoin College and, after spending time in Europe, he became a professor at Bowdoin and at Harvard College. His first major poetry collections were Voices of Other Poems. Longfellow retired from teaching in 1854 to focus on his writing, he lived the remainder of his life in a former Revolutionary War headquarters of George Washington in Cambridge, Massachusetts, his first wife Mary Potter died in 1835 after a miscarriage. His second wife Frances Appleton died in 1861 after sustaining burns. After her death, Longfellow had difficulty writing poetry for a time and focused on translating works from foreign languages, he died in 1882. Longfellow wrote many lyric poems known for their musicality and presenting stories of mythology and legend.
He became the most popular American poet of his day and had success overseas. He has been criticized, for imitating European styles and writing for the masses. Longfellow was born on February 27, 1807 to Stephen Longfellow and Zilpah Longfellow in Portland, Maine a district of Massachusetts, he grew up in -- Longfellow House. His father was a lawyer, his maternal grandfather was Peleg Wadsworth, a general in the American Revolutionary War and a Member of Congress, his mother was descended from a passenger on the Mayflower. He was named after his mother's brother Henry Wadsworth, a Navy lieutenant who had died three years earlier at the Battle of Tripoli, he was the second of eight children. Longfellow's ancestors were English colonists, they included Mayflower Pilgrims Richard Warren, William Brewster, John and Priscilla Alden, as well as Elizabeth Pabodie, the first child born in Plymouth Colony. Longfellow attended a dame school at the age of three and was enrolled by age six at the private Portland Academy.
In his years there, he earned a reputation as being studious and became fluent in Latin. His mother encouraged his enthusiasm for reading and learning, introducing him to Robinson Crusoe and Don Quixote, he published his first poem in the Portland Gazette on November 17, 1820, a patriotic and historical four-stanza poem called "The Battle of Lovell's Pond". He studied at the Portland Academy until age 14, he spent much of his summers as a child at his grandfather Peleg's farm in Maine. In the fall of 1822, 15 year-old Longfellow enrolled at Bowdoin College in Brunswick, along with his brother Stephen, his grandfather was a founder of the college and his father was a trustee. There Longfellow met Nathaniel Hawthorne, he boarded with a clergyman for a time before rooming on the third floor in 1823 of what is now known as Winthrop Hall. He joined a group of students with Federalist leanings. In his senior year, Longfellow wrote to his father about his aspirations: I will not disguise it in the least….
The fact is, I most eagerly aspire after future eminence in literature, my whole soul burns most ardently after it, every earthly thought centres in it…. I am confident in believing, that if I can rise in the world it must be by the exercise of my talents in the wide field of literature, he pursued his literary goals by submitting poetry and prose to various newspapers and magazines due to encouragement from Professor Thomas Cogswell Upham. He published nearly 40 minor poems between January 1824 and his graduation in 1825. About 24 of them were published in the short-lived Boston periodical The United States Literary Gazette; when Longfellow graduated from Bowdoin, he was ranked fourth in the class and had been elected to Phi Beta Kappa. He gave the student commencement address. After graduating in 1825, Longfellow was offered a job as professor of modern languages at his alma mater. An apocryphal story claims that college trustee Benjamin Orr had been impressed by Longfellow's translation of Horace and hired him under the condition that he travel to Europe to study French and Italian.
Whatever the catalyst, Longfellow began his tour of Europe in May 1826 aboard the ship Cadmus. His time abroad lasted three years and cost his father $2,604.24. He traveled to France, Italy, back to France to England before returning to the United States in mid-August 1829. While overseas, he learned French, Spanish and German without formal instruction. In Madrid, he spent time with Washington Irving and was impressed by the author's work ethic. Irving encouraged the young Longfellow to pursue writing. While in Spain, Longfellow was saddened to learn that his favorite sister Elizabeth had died of tuberculosis at the age of 20 that May. On August 27, 1829, he wrote to the president of Bowdoin that he was turning down the professorship because he considered the $600 salary "disproportionate to the duties required"; the trustees raised his salary to $800 with an additional $100 to serve as the college's librarian, a post which required one hour of work per day. During his years teaching at the college, he translated textbooks from French and Spanish.
He published the travel book Outre-Mer: A Pilgrimage Beyond the Sea in serial form before a book edition was released in 1835. Shortly
Dublin is the capital and largest city of Ireland. It is on the east coast of Ireland, in the province of Leinster, at the mouth of the River Liffey, is bordered on the south by the Wicklow Mountains, it has an urban area population of 1,173,179, while the population of the Dublin Region, as of 2016, was 1,347,359, the population of the Greater Dublin area was 1,904,806. There is archaeological debate regarding where Dublin was established by the Gaels in or before the 7th century AD. Expanded as a Viking settlement, the Kingdom of Dublin, the city became Ireland's principal settlement following the Norman invasion; the city expanded from the 17th century and was the second largest city in the British Empire before the Acts of Union in 1800. Following the partition of Ireland in 1922, Dublin became the capital of the Irish Free State renamed Ireland. Dublin is a historical and contemporary centre for education, the arts and industry; as of 2018 the city was listed by the Globalization and World Cities Research Network as a global city, with a ranking of "Alpha −", which places it amongst the top thirty cities in the world.
The name Dublin comes from the Irish word Dubhlinn, early Classical Irish Dubhlind/Duibhlind, from dubh meaning "black, dark", lind "pool", referring to a dark tidal pool. This tidal pool was located where the River Poddle entered the Liffey, on the site of the castle gardens at the rear of Dublin Castle. In Modern Irish the name is Duibhlinn, Irish rhymes from County Dublin show that in Dublin Leinster Irish it was pronounced Duílinn; the original pronunciation is preserved in the names for the city in other languages such as Old English Difelin, Old Norse Dyflin, modern Icelandic Dyflinn and modern Manx Divlyn as well as Welsh Dulyn. Other localities in Ireland bear the name Duibhlinn, variously anglicized as Devlin and Difflin. Scribes using the Gaelic script wrote bh with a dot over the b, rendering Duḃlinn or Duiḃlinn; those without knowledge of Irish omitted the dot. Variations on the name are found in traditionally Gaelic-speaking areas of Scotland, such as An Linne Dhubh, part of Loch Linnhe.
It is now thought that the Viking settlement was preceded by a Christian ecclesiastical settlement known as Duibhlinn, from which Dyflin took its name. Beginning in the 9th and 10th century, there were two settlements; the Viking settlement of about 841, a Gaelic settlement, Áth Cliath further up river, at the present day Father Mathew Bridge, at the bottom of Church Street. Baile Átha Cliath, meaning "town of the hurdled ford", is the common name for the city in modern Irish. Áth Cliath is a place name referring to a fording point of the River Liffey near Father Mathew Bridge. Baile Átha Cliath was an early Christian monastery, believed to have been in the area of Aungier Street occupied by Whitefriar Street Carmelite Church. There are other towns of the same name, such as Àth Cliath in East Ayrshire, Anglicised as Hurlford; the area of Dublin Bay has been inhabited by humans since prehistoric times, but the writings of Ptolemy in about AD 140 provide the earliest reference to a settlement there.
He called it Eblana polis. Dublin celebrated its'official' millennium in 1988, meaning the Irish government recognised 988 as the year in which the city was settled and that this first settlement would become the city of Dublin, it is now thought the Viking settlement of about 841 was preceded by a Christian ecclesiastical settlement known as Duibhlinn, from which Dyflin took its name. Beginning in the 9th and 10th century, there were two settlements which became the modern Dublin; the subsequent Scandinavian settlement centred on the River Poddle, a tributary of the Liffey in an area now known as Wood Quay. The Dubhlinn was a pool on the lowest stretch of the Poddle, used to moor ships; this pool was fully infilled during the early 18th century, as the city grew. The Dubhlinn lay where the Castle Garden is now located, opposite the Chester Beatty Library within Dublin Castle. Táin Bó Cuailgne refers to Dublind rissa ratter Áth Cliath, meaning "Dublin, called Ath Cliath". Dublin was established as a Viking settlement in the 10th century and, despite a number of attacks by the native Irish, it remained under Viking control until the Norman invasion of Ireland was launched from Wales in 1169.
It was upon the death of Muirchertach Mac Lochlainn in early 1166 that Ruaidrí Ua Conchobair, King of Connacht, proceeded to Dublin and was inaugurated King of Ireland without opposition. According to some historians, part of the city's early economic growth is attributed to a trade in slaves. Slavery in Ireland and Dublin reached its pinnacle in the 10th centuries. Prisoners from slave raids and kidnappings, which captured men and children, brought revenue to the Gaelic Irish Sea raiders, as well as to the Vikings who had initiated the practice; the victims came from Wales, England and beyond. The King of Leinster, Diarmait Mac Murchada, after his exile by Ruaidhrí, enlisted the help of Strongbow, the Earl of Pembroke, to conquer Dublin. Following Mac Murrough's death, Strongbow declared himself King of Leinster after gaining control of the city. In response to Strongbow's successful invasion, King Henry II of England affirmed his ultimate sovereignty by mou
