It is characterized by its use of a steady, prominent beat and a heavy emphasis on bass and drums, with prominent use of synthesized instrumentation, strings, and horns. The lyrics of disco songs often revolve around love, romance, and dancing. Disco music is often associated with the fashion, dancing, and club culture of the 1970s, and it has had a lasting influence on subsequent dance and pop music genres.
