Canada is a country in the northern part of North America. Its ten provinces and three territories extend from the Atlantic to the Pacific and northward into the Arctic Ocean, covering 9.98 million square kilometres, making it the world's second-largest country by total area. Canada's southern border with the United States is the world's longest bi-national land border, its capital is Ottawa, its three largest metropolitan areas are Toronto and Vancouver. As a whole, Canada is sparsely populated, the majority of its land area being dominated by forest and tundra, its population is urbanized, with over 80 percent of its inhabitants concentrated in large and medium-sized cities, many near the southern border. Canada's climate varies across its vast area, ranging from arctic weather in the north, to hot summers in the southern regions, with four distinct seasons. Various indigenous peoples have inhabited what is now Canada for thousands of years prior to European colonization. Beginning in the 16th century and French expeditions explored, settled, along the Atlantic coast.
As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces; this began an accretion of provinces and territories and a process of increasing autonomy from the United Kingdom. This widening autonomy was highlighted by the Statute of Westminster of 1931 and culminated in the Canada Act of 1982, which severed the vestiges of legal dependence on the British parliament. Canada is a parliamentary democracy and a constitutional monarchy in the Westminster tradition, with Elizabeth II as its queen and a prime minister who serves as the chair of the federal cabinet and head of government; the country is a realm within the Commonwealth of Nations, a member of the Francophonie and bilingual at the federal level. It ranks among the highest in international measurements of government transparency, civil liberties, quality of life, economic freedom, education.
It is one of the world's most ethnically diverse and multicultural nations, the product of large-scale immigration from many other countries. Canada's long and complex relationship with the United States has had a significant impact on its economy and culture. A developed country, Canada has the sixteenth-highest nominal per capita income globally as well as the twelfth-highest ranking in the Human Development Index, its advanced economy is the tenth-largest in the world, relying chiefly upon its abundant natural resources and well-developed international trade networks. Canada is part of several major international and intergovernmental institutions or groupings including the United Nations, the North Atlantic Treaty Organization, the G7, the Group of Ten, the G20, the North American Free Trade Agreement and the Asia-Pacific Economic Cooperation forum. While a variety of theories have been postulated for the etymological origins of Canada, the name is now accepted as coming from the St. Lawrence Iroquoian word kanata, meaning "village" or "settlement".
In 1535, indigenous inhabitants of the present-day Quebec City region used the word to direct French explorer Jacques Cartier to the village of Stadacona. Cartier used the word Canada to refer not only to that particular village but to the entire area subject to Donnacona. From the 16th to the early 18th century "Canada" referred to the part of New France that lay along the Saint Lawrence River. In 1791, the area became two British colonies called Upper Canada and Lower Canada collectively named the Canadas. Upon Confederation in 1867, Canada was adopted as the legal name for the new country at the London Conference, the word Dominion was conferred as the country's title. By the 1950s, the term Dominion of Canada was no longer used by the United Kingdom, which considered Canada a "Realm of the Commonwealth"; the government of Louis St. Laurent ended the practice of using'Dominion' in the Statutes of Canada in 1951. In 1982, the passage of the Canada Act, bringing the Constitution of Canada under Canadian control, referred only to Canada, that year the name of the national holiday was changed from Dominion Day to Canada Day.
The term Dominion was used to distinguish the federal government from the provinces, though after the Second World War the term federal had replaced dominion. Indigenous peoples in present-day Canada include the First Nations, Métis, the last being a mixed-blood people who originated in the mid-17th century when First Nations and Inuit people married European settlers; the term "Aboriginal" as a collective noun is a specific term of art used in some legal documents, including the Constitution Act 1982. The first inhabitants of North America are hypothesized to have migrated from Siberia by way of the Bering land bridge and arrived at least 14,000 years ago; the Paleo-Indian archeological sites at Old Crow Flats and Bluefish Caves are two of the oldest sites of human habitation in Canada. The characteristics of Canadian indigenous societies included permanent settlements, complex societal hierarchies, trading networks; some of these cultures had collapsed by the time European explorers arrived in the late 15th and early 16th centuries and have only been discovered through archeological investigations.
The indigenous population at the time of the first European settlements is estimated to have been between 200,000
A disc jockey abbreviated as DJ, is a person who plays existing recorded music for a live audience. Most common types of DJs include radio DJ, club DJ who performs at a nightclub or music festival and turntablist who uses record players turntables, to manipulate sounds on phonograph records; the disc in disc jockey referred to gramophone records, but now DJ is used as an all-encompassing term to describe someone who mixes recorded music from any source, including cassettes, CDs or digital audio files on a CDJ or laptop. The title DJ is used by DJs in front of their real names or adopted pseudonyms or stage names. In recent years it has become common for DJs to be featured as the credited artist on tracks they produced despite having a guest vocalist that performs the entire song: like for example Uptown Funk. DJs use audio equipment that can play at least two sources of recorded music and mix them together to create seamless transitions between recordings and develop unique mixes of songs; this involves aligning the beats of the music sources so their rhythms do not clash when played together or to enable a smooth transition from one song to another.
DJs use specialized DJ mixers, small audio mixers with crossfader and cue functions to blend or transition from one song to another. Mixers are used to pre-listen to sources of recorded music in headphones and adjust upcoming tracks to mix with playing music. DJ software can be used with a DJ controller device to mix audio files on a computer instead of a console mixer. DJs may use a microphone to speak to the audience; the "disc" in "disc jockey" referred to gramophone records, but now "DJ" is used as an all-encompassing term to describe someone who mixes recorded music from any source, including vinyl records, cassettes, CDs, or digital audio files stored on USB stick or laptop. DJs perform for a live audience in a nightclub or dance club or a TV, radio broadcast audience, or in the 2010s, an online radio audience. DJs create mixes and tracks that are recorded for sale and distribution. In hip hop music, DJs may create beats, using percussion breaks and other musical content sampled from pre-existing records.
In hip hop, rappers and MCs use. DJs use equipment that can play at least two sources of recorded music and mix them together; this allows the DJ to create seamless transitions between recordings and develop unique mixes of songs. This involves aligning the beats of the music sources so their rhythms do not clash when they are played together, either so two records can be played at the same time, or to enable the DJ to make a smooth transition from one song to another. An important tool for DJs is the specialized DJ mixer, a small audio mixer with a crossfader and cue functions; the crossfader enables the DJ to transition from one song to another. The cue knobs or switches allow the DJ to listen to a source of recorded music in headphones before playing it for the live club or broadcast audience. Previewing the music in headphones helps the DJ pick the next track they want to play, cue up the track to the desired starting location, align the two tracks' beats in traditional situations where auto sync technology is not being used.
This process ensures that the selected song will mix well with the playing music. DJs may use a microphone to speak to the audience; the title "DJ" is commonly used by DJs in front of their real names or adopted pseudonyms or stage names as a title to denote their profession. Some DJs focus on creating a good mix of songs for the club dancers or radio audience. Other DJs use turntablism techniques such as scratching, in which the DJ or turntablist manipulates the record player turntable to create new rhythms and sounds. DJs need to have a mixture of artistic and technical skills for their profession, because they have to understand both the creative aspects of making new musical beats and tracks, the technical aspects of using mixing consoles, professional audio equipment, and, in the 2010s, digital audio workstations and other computerized music gear. In many types of DJing, including club DJing and radio/TV DJing, a DJ has to have charisma and develop a good rapport with the audience. Professional DJs specialize in a specific genre of music, such as house music or hip hop music.
DJs have an extensive knowledge about the music they specialize in. Many DJs are avid music collectors of rare or obscure tracks and records. Radio DJs or radio personalities introduce and play music broadcast on AM, FM, digital or Internet radio stations. Club DJs referred as DJs in general, play music at musical events, such as parties at music venues or bars, music festivals and private events. Club DJs mix music recordings from two or more sources using different mixing techniques in order to produce non-stopping flow of music. One key technique used for seamlessly transitioning from one song to another is beatmatching. A DJ who plays and mixes one specific music genre is given the title of that genre; the quality of a DJ performance consists of two main features: technical skills, or how well can DJ operate the equipment and produce sm
