Atonality is simply the absence of tonality, tonality being the musical system based on major and minor keys, it is a condition of music in which the constructs of the music do not “live” within the confines of a particular key signature, scale, or mode. To the uninitiated listener, atonal music can sound like chaotic, random noise.
