ABSTRACT
In the 20th century, music began to realise its potential as the most universal medium of communication. Music is a way of transmitting and reflecting emotion. Of all the art forms, music may be the most difficult to describe in words, but perhaps because of this, it is also the one that most easily transcends barriers of nationality and language. This encyclopedia looks at how music, in all its rich variety, has become part of the daily life of most of humankind, and how the international and mass appeal of music has changed its form forever. In the process, it helps us understand this unique feature of modern life.
