Classical Music

• The term "classical" is something of a misnomer, because the word actually defines a specific time period of music rather than a complete genre. Nevertheless, for the past five decades, the classical music genre encompasses all music written for instrumental ensemble and voice. Classical music is also sometimes called "concert" and "art" music. Classical music is typically read from notated scores, which distinguishes it from other genres such as jazz. Classical music is performed by symphonies, opera companies, chamber music groups and soloists.
  
  

Jazz

• Jazz music can trace its roots to a variety of international cultures; many of its elements stem from Africa. Jazz is written for a variety of instrumental ensembles, some of which include vocal support. Jazz is different from classical music in that it is typically improvised following the introduction of a "head," or short thematic motif. Jazz is performed in concert halls and nightclubs around the world.
  
  

Rock

• Rock music typically involves a small group of amplified instruments, consisting of a bass guitar, an electric guitar, a drum set and a vocalist. Keyboards and synthesizers also make occasional appearances. Rock music traces its origins to mid-20th century America, with artists such as Elvis Presley and Chuck Berry. At the time, rock music was a stunning departure from the big band and swing music that had filled American dance halls previously.
  
  

Pop

• The genre of "pop" music is characterized by catchy, short songs that typically mirror the trends and sentiments of the public at the time. Pop music is not known for its longevity, but rather for its ability to entertain the public at large over the radio, Internet and at concert venues. Pop music typically incorporates a high production value, involving music videos, highly choreographed dance routines and large-scale album production.
