Classical music
–
Classical music is art music produced or rooted in the traditions of Western music, including both liturgical and secular music. The central norms of this tradition became codified between 1550 and 1900, which is known as the common-practice period, Western staff notation is used by composers to indicate to the performer the pitches, tempo, meter and rhythms for a piece of music. This can leave less room for such as improvisation and ad libitum ornamentation. The term classical music did not appear until the early 19th century, the earliest reference to classical music recorded by the Oxford English Dictionary is from about 1836. This score typically determines details of rhythm, pitch, and, the written quality of the music has enabled a high level of complexity within them, J. S. The use of written notation also preserves a record of the works, Musical notation enables 2000s-era performers to sing a choral work from the 1300s Renaissance era or a 1700s Baroque concerto with many of the features of the music being reproduced. That said, the score does not provide complete and exact instructions on how to perform a historical work, even if the tempo is written with an Italian instruction, we do not know exactly how fast the piece should be played. Bach was particularly noted for his complex improvisations, during the Classical era, the composer-performer Mozart was noted for his ability to improvise melodies in different styles. During the Classical era, some virtuoso soloists would improvise the cadenza sections of a concerto, during the Romantic era, Beethoven would improvise at the piano. The instruments currently used in most classical music were largely invented before the mid-19th century and they consist of the instruments found in an orchestra or in a concert band, together with several other solo instruments. The symphony orchestra is the most widely known medium for music and includes members of the string, woodwind, brass. The concert band consists of members of the woodwind, brass and it generally has a larger variety and number of woodwind and brass instruments than the orchestra but does not have a string section. However, many bands use a double bass. Many of the used to perform medieval music still exist. Medieval instruments included the flute, the recorder and plucked string instruments like the lute. As well, early versions of the organ, fiddle, Medieval instruments in Europe had most commonly been used singly, often self accompanied with a drone note, or occasionally in parts. From at least as early as the 13th century through the 15th century there was a division of instruments into haut, during the earlier medieval period, the vocal music from the liturgical genre, predominantly Gregorian chant, was monophonic, using a single, unaccompanied vocal melody line. Polyphonic vocal genres, which used multiple independent vocal melodies, began to develop during the medieval era, becoming prevalent by the later 13th

Western culture
–
The term also applies beyond Europe, to countries and cultures whose histories are strongly connected to Europe by immigration, colonization, or influence. For example, Western Culture includes countries in the Americas and Australasia, whose language, before the Cold War era, the traditional Western viewpoint identified Western Civilization with the Western Christian countries and culture. Ancient Greece is considered the birthplace of Western culture, with the worlds first democratic system of government and major advances in philosophy, science, Greece was followed by Rome, which made key contributions in law, government, engineering and political organization. European culture developed with a range of philosophy, medieval scholasticism, and mysticism. Rational thinking developed through an age of change and formation, with the experiments of the Enlightenment. More often an ideology is what will be used to categorize it as a Western society. There is some disagreement about what nations should or should not be included in the category, many parts of the Eastern Roman Empire are considered Western today but were Eastern in the past. Since the context is highly biased and context-dependent, there is no agreed definition what the West is and it is difficult to determine which individuals fit into which category and the East–West contrast is sometimes criticized as relativistic and arbitrary. Globalism has spread Western ideas so widely that almost all cultures are, to some extent. Stereotyped views of the West have been labeled Occidentalism, paralleling Orientalism—the term for the 19th-century stereotyped views of the East, as Europe discovered the wider world, old concepts adapted. The area that had formerly considered the Orient became the Near East, as the interests of the European powers interfered with Meiji Japan and Qing China for the first time. Thus, the Sino-Japanese War in 1894–1895 occurred in the Far East, the Greeks contrasted themselves to their Eastern neighbors, such as the Trojans in Iliad, setting an example for later contrasts between east and west. In the Middle Ages, the Near East provided a contrast to the West, concepts of what is the West arose out of legacies of the Western Roman Empire and the Eastern Roman Empire. Later, ideas of the west were formed by the concepts of Latin Christendom, Western culture is neither homogeneous nor unchanging. As with all cultures, it has evolved and gradually changed over time. Nevertheless, it is possible to follow the evolution and history of the West, and appreciate its similarities and differences, its borrowings from, and contributions to, other cultures of humanity. Nevertheless, the Greeks felt they were the most civilized and saw themselves as something between the wild barbarians of most of Europe and the soft, slavish Middle-Easterners. In the meantime, however, Greece, under Alexander, had become a capital of the East, the Celts also created some significant literature in the ancient world whenever they were given the opportunity

Ancient Greek
–
Ancient Greek includes the forms of Greek used in ancient Greece and the ancient world from around the 9th century BC to the 6th century AD. It is often divided into the Archaic period, Classical period. It is antedated in the second millennium BC by Mycenaean Greek, the language of the Hellenistic phase is known as Koine. Koine is regarded as a historical stage of its own, although in its earliest form it closely resembled Attic Greek. Prior to the Koine period, Greek of the classic and earlier periods included several regional dialects, Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical phases of the language, Ancient Greek was a pluricentric language, divided into many dialects. The main dialect groups are Attic and Ionic, Aeolic, Arcadocypriot, some dialects are found in standardized literary forms used in literature, while others are attested only in inscriptions. There are also several historical forms, homeric Greek is a literary form of Archaic Greek used in the epic poems, the Iliad and Odyssey, and in later poems by other authors. Homeric Greek had significant differences in grammar and pronunciation from Classical Attic, the origins, early form and development of the Hellenic language family are not well understood because of a lack of contemporaneous evidence. Several theories exist about what Hellenic dialect groups may have existed between the divergence of early Greek-like speech from the common Proto-Indo-European language and the Classical period and they have the same general outline, but differ in some of the detail. The invasion would not be Dorian unless the invaders had some relationship to the historical Dorians. The invasion is known to have displaced population to the later Attic-Ionic regions, the Greeks of this period believed there were three major divisions of all Greek people—Dorians, Aeolians, and Ionians, each with their own defining and distinctive dialects. Often non-west is called East Greek, Arcadocypriot apparently descended more closely from the Mycenaean Greek of the Bronze Age. Boeotian had come under a strong Northwest Greek influence, and can in some respects be considered a transitional dialect, thessalian likewise had come under Northwest Greek influence, though to a lesser degree. Most of the dialect sub-groups listed above had further subdivisions, generally equivalent to a city-state and its surrounding territory, Doric notably had several intermediate divisions as well, into Island Doric, Southern Peloponnesus Doric, and Northern Peloponnesus Doric. The Lesbian dialect was Aeolic Greek and this dialect slowly replaced most of the older dialects, although Doric dialect has survived in the Tsakonian language, which is spoken in the region of modern Sparta. Doric has also passed down its aorist terminations into most verbs of Demotic Greek, by about the 6th century AD, the Koine had slowly metamorphosized into Medieval Greek

Accidental (music)
–
In music, an accidental is a note of a pitch that is not a member of the scale or mode indicated by the most recently applied key signature. In musical notation, the sharp, flat, and natural symbols, among others, in the measure where it appears, an accidental sign raises or lowers the immediately following note from its normal pitch, overriding sharps or flats in the key signature. A note is raised or lowered by a semitone, although microtonal music may use fractional accidental signs. One occasionally sees double sharps or flats, which raise or lower the note by a whole tone. Accidentals apply within the measure and octave in which appear, unless canceled by another accidental sign. If a note has an accidental and the note is repeated in a different octave within the same measure, the accidental does not apply to the same note of the different octave. The modern accidental signs derive from the two forms of the letter b used in Gregorian chant manuscripts to signify the two pitches of B, the only note that could be altered. The round b became the sign, while the square b diverged into the sharp. Sometimes the black keys on a keyboard are called accidentals or sharps. In most cases, a sharp raises the pitch of a note one semitone while a flat lowers it a semitone, a natural is used to cancel the effect of a flat or sharp. This system of accidentals operates in conjunction with the key signature, whose effect continues throughout an entire piece, an accidental can also be used to cancel a previous accidental or reinstate the flats or sharps of the key signature. Accidentals apply to subsequent notes on the staff position for the remainder of the measure where they occur, unless explicitly changed by another accidental. Once a barline is passed, the effect of the accidental ends, subsequent notes at the same staff position in the second or later bars are not affected by the accidental carried through with the tied note. Though this convention is still in use particularly in music, it may be cumbersome in music that features frequent accidentals. As a result, a system of note-for-note accidentals has been adopted. Accidentals are not repeated for repeated notes unless one or more different pitches intervene, if a sharp or flat pitch is followed directly by its natural form, a natural is used. Cautionary accidentals or naturals may be used to clarify ambiguities, because seven of the twelve notes of the chromatic equal-tempered scale are naturals this system can significantly reduce the number of naturals required in a notated passage. Thus, the effect of the accidental must be understood in relation to the meaning of the notes staff position

Sharp (music)
–
In music, sharp, dièse, or diesis means higher in pitch. More specifically, in musical notation, sharp means higher in pitch by a semitone, and has a sharp symbol, ♯. Sharp is contrasted with flat, which refers to a lowering of pitch, intonation may be flat, sharp, or both, successively or simultaneously. Under twelve-tone equal temperament, B♯, for instance, sounds the same as, or is equivalent to, C natural. In other tuning systems, such enharmonic equivalences in general do not exist, to allow extended just intonation, composer Ben Johnston uses a sharp to indicate a note is raised 70.6 cents, or a flat to indicate a note is lowered 70.6 cents. In tuning, sharp can also slightly higher in pitch. If two simultaneous notes are out of tune, the higher-pitched one is said to be sharp with respect to the other. Furthermore, the verb sharpen means raise the frequency of a note, double sharps also exist, these are denoted by the symbol and raise a note by two semitones, or one whole tone. They should not be confused with a ghost note, less often one will encounter other sharps. A half sharp raises a note by a quarter tone =50 cents, a sharp and a half raises a note by three quarter tones =150 cents and may be denoted. Although very uncommon, a triple sharp can sometimes be found and it raises a note by three semitones. The sharp symbol may be confused with the number sign, both signs have two sets of parallel double-lines. However, a correctly drawn sharp sign must have two slanted parallel lines which rise from left to right, to avoid being obscured by the staff lines, the number sign, in contrast, has two compulsory horizontal strokes in this place. In addition, while the sharp also always has two vertical lines, the number sign may or may not contain perfectly vertical lines. The order of sharps in key signature notation is F♯, C♯, G♯, D♯, A♯, E♯, B♯, each extra sharp being added successively in the sequence of major keys. Similarly the order of flats is based on the natural notes in reverse order, B♭, E♭, A♭, D♭, G♭, C♭, F♭, encountered in the following series of major keys. In the above progression, key C♯ may be conveniently written as the harmonically equivalent key D♭

Interval (music)
–
In music theory, an interval is the difference between two pitches. In Western music, intervals are most commonly differences between notes of a diatonic scale, the smallest of these intervals is a semitone. Intervals smaller than a semitone are called microtones and they can be formed using the notes of various kinds of non-diatonic scales. Some of the very smallest ones are called commas, and describe small discrepancies, observed in some tuning systems, Intervals can be arbitrarily small, and even imperceptible to the human ear. In physical terms, an interval is the ratio between two sonic frequencies, for example, any two notes an octave apart have a frequency ratio of 2,1. This means that successive increments of pitch by the same result in an exponential increase of frequency. For this reason, intervals are often measured in cents, a derived from the logarithm of the frequency ratio. In Western music theory, the most common naming scheme for intervals describes two properties of the interval, the quality and number, examples include the minor third or perfect fifth. These names describe not only the difference in semitones between the upper and lower notes, but also how the interval is spelled, the importance of spelling stems from the historical practice of differentiating the frequency ratios of enharmonic intervals such as G–G♯ and G–A♭. The size of an interval can be represented using two alternative and equivalently valid methods, each appropriate to a different context, frequency ratios or cents, the size of an interval between two notes may be measured by the ratio of their frequencies. When a musical instrument is tuned using a just intonation tuning system, Intervals with small-integer ratios are often called just intervals, or pure intervals. Most commonly, however, musical instruments are tuned using a different tuning system. As a consequence, the size of most equal-tempered intervals cannot be expressed by small-integer ratios, for instance, an equal-tempered fifth has a frequency ratio of 2 7⁄12,1, approximately equal to 1.498,1, or 2.997,2. For a comparison between the size of intervals in different tuning systems, see section Size in different tuning systems, the standard system for comparing interval sizes is with cents. The cent is a unit of measurement. If frequency is expressed in a scale, and along that scale the distance between a given frequency and its double is divided into 1200 equal parts, each of these parts is one cent. In twelve-tone equal temperament, a system in which all semitones have the same size. Hence, in 12-TET the cent can be defined as one hundredth of a semitone

Octave
–
In music, an octave or perfect octave is the interval between one musical pitch and another with half or double its frequency. It is defined by ANSI as the unit of level when the base of the logarithm is two. The octave relationship is a phenomenon that has been referred to as the basic miracle of music. The most important musical scales are written using eight notes. For example, the C major scale is typically written C D E F G A B C, two notes separated by an octave have the same letter name and are of the same pitch class. Three commonly cited examples of melodies featuring the perfect octave as their opening interval are Singin in the Rain, Somewhere Over the Rainbow, the interval between the first and second harmonics of the harmonic series is an octave. The octave has occasionally referred to as a diapason. To emphasize that it is one of the intervals, the octave is designated P8. The octave above or below a note is sometimes abbreviated 8a or 8va, 8va bassa. For example, if one note has a frequency of 440 Hz, the note one octave above is at 880 Hz, the ratio of frequencies of two notes an octave apart is therefore 2,1. Further octaves of a note occur at 2n times the frequency of that note, such as 2,4,8,16, etc. and the reciprocal of that series. For example,55 Hz and 440 Hz are one and two away from 110 Hz because they are 1⁄2 and 4 times the frequency, respectively. After the unison, the octave is the simplest interval in music, the human ear tends to hear both notes as being essentially the same, due to closely related harmonics. Notes separated by a ring together, adding a pleasing sound to music. For this reason, notes an octave apart are given the note name in the Western system of music notation—the name of a note an octave above A is also A. The conceptualization of pitch as having two dimensions, pitch height and pitch class, inherently include octave circularity, thus all C♯s, or all 1s, in any octave are part of the same pitch class. Octave equivalency is a part of most advanced cultures, but is far from universal in primitive. The languages in which the oldest extant written documents on tuning are written, leon Crickmore recently proposed that The octave may not have been thought of as a unit in its own right, but rather by analogy like the first day of a new seven-day week

Interval ratio
–
In music, an interval ratio is a ratio of the frequencies of the pitches in a musical interval. For example, a just perfect fifth is 3,2,1.5, if the A above middle C is 440 Hz, the perfect fifth above it would be E, at 660 Hz, while the equal tempered E5 is 659.255 Hz. Ratios have a relationship to string length, for example stopping a string at two-thirds its length produces a pitch one. Intervals may be ranked by relative consonance and dissonance, as such ratios with lower integers are generally more consonant than intervals with higher integers. For example,2,1,4,3,9,8,65536,59049, consonance and dissonance may more subtly be defined by limit, wherein the ratios whose limit, which includes its integer multiples, is lower are generally more consonant. For example, the 3-limit 128,81 and the 7-limit 14,9, despite having larger integers 128,81 is less dissonant than 14,9, as according to limit theory. For ease of comparison intervals may also be measured in cents, for example, the just perfect fifth is 701.955 cents while the equal tempered perfect fifth is 700 cents. Frequency ratios are used to describe intervals in both Western and non-Western music. When a musical instrument is tuned using a just intonation tuning system, intervals with small-integer ratios are often called just intervals, or pure intervals. To most people, just intervals sound consonant, i. e. pleasant, although the size of equally tuned intervals is typically similar to that of just intervals, in most cases it cannot be expressed by small-integer ratios. For instance, a tempered perfect fifth has a frequency ratio of about 1.4983,1. For a comparison between the size of intervals in different tuning systems, see section Size in different tuning systems

Just intonation
–
In music, just intonation or pure intonation is any musical tuning in which the frequencies of notes are related by ratios of small whole numbers. Any interval tuned in this way is called a pure or just interval, pure intervals are important in music because they correspond to the vibrational patterns found in physical objects which correlate to human perception. The two notes in any just interval are members of the harmonic series. Frequency ratios involving large integers such as 1024,729 are not generally said to be justly tuned, the Indian classical music system uses just intonation tuning as codified in the Natya Shastra. Various societies perceive pure intervals as pleasing or satisfying consonant and, conversely, however, various societies do not have these associations. Just intonation can be contrasted and compared with equal temperament, which dominates Western instruments of fixed pitch, however, except for doubling of frequencies, no other intervals are exact ratios of small integers. Each just interval differs a different amount from its analogous, equally tempered interval, justly tuned intervals can be written as either ratios, with a colon, or as fractions, with a solidus. For example, two tones, one at 300 hertz, and the other at 200 hertz are both multiples of 100 Hz and as members of the harmonic series built on 100 Hz. Thus 3,2, known as a fifth, may be defined as the musical interval between the second and third harmonics of any fundamental pitch. Just intonation An A-major scale, followed by three major triads, and then a progression of fifths in just intonation, equal temperament An A-major scale, followed by three major triads, and then a progression of fifths in equal temperament. By listening to the file, and then listening to this one, one might be able to hear the beating in this file. Equal temperament and just intonation compared A pair of major thirds, the first in each pair is in equal temperament, the second is in just intonation. Equal temperament and just intonation compared with square waveform A pair of major chords, the first is in equal temperament, the second is in just intonation. The pair of chords is repeated with a transition from equal temperament to just temperament between the two chords, in the equal temperament chords a roughness or beating can be heard at about 4 Hz and about 0.8 Hz. In the just intonation triad, this roughness is absent, the square waveform makes the difference between equal and just temperaments more obvious. Harmonic intervals come naturally to horns, vibrating strings, and in human singing voices. Pythagorean tuning, perhaps the first tuning system to be theorized in the West, is a system in all tones can be found using powers of the ratio 3,2. It is easier to think of this system as a cycle of fifths
