History :
Music is found in every known culture, organization past and present, varying commonly between times and places. Since individuals from different parts of the world, including the most isolated tribal groups, have a form of music, it may be concluded that music is likely to have been present in the ancestral population prior to the dispersal of humans around the globe. As a result, music may have been in existence for at least 55,000 years and the first music may have been invented in Africa and then evolved to become an essential part of human life.
During the 20th century there was a vast increase in the variety of music that people had access to. Prior to the invention of mass market gramophone records (developed in 1892) and radio broadcasting (first commercially done ca. 1919–20), people mainly listened to music at live Classical music concerts or musical theatre shows, which were too expensive for many lower-income people; on early phonograph players (a technology invented in 1877 which was not mass-marketed until the mid-1890s); or by individuals performing music or singing songs on an amateur basis at home, using sheet music, which required the ability to sing, play, and read music. These were skills that tended to be limited to middle-class and upper-classindividuals. With the mass-market availability of gramophone records and radio broadcasts, listeners could purchase recordings of, or listen on radio to recordings or live broadcasts of a huge variety of songs and musical pieces from around the globe. This enabled a much wider range of the population to listen to performances of Classical musicsymphonies and operas that they would not be able to hear live, either due to not being able to afford live-concert tickets or because such music was not performed in their region.
