Definition
Atonality is the absence of a tonal center or key in music. It rejects the traditional harmonic structure of tonality, creating music that sounds dissonant and unstable. There's no 'home base' or central tone to gravitate towards. Think of it as musical anarchy, where there are no fixed rules or expectations. Atonal music often sounds chaotic and unpredictable. Atonality challenges listeners to embrace new sonic landscapes beyond traditional harmony.
