Experimental music

Experimental music, or Avant-garde music, is any music that challenges the commonly accepted notions of what music is. It may do this by trying new harmonies or adding other new sounds, and by using new forms and structures, for example. Experimental music often sounds unpleasant or abrasive to people who are not used to hearing it.
