Twelve-tone music is a technique of composition in which all twelve notes of the chromatic scale are arranged in a fixed order and used equally, thus creating a melody with no discernible tonal center. This type of atonal music was first invented by Austrian composer Arnold Schoenberg and later refined by other composers such as Alban Berg and Anton Webern. The main idea behind twelve-tone music is that any note can succeed any other, so long as it doesn't repeat an earlier pitch. This eliminates the need for a tonal center, or "key," around which a piece of music is based. The result is music that is often seen as more intellectual or challenging than traditional tonal music.
