Definition
Tonality refers to the organization of music around a central tone (the tonic) or key. It creates a sense of harmonic stability and expectation, like a musical 'home base.' Melodies and harmonies gravitate towards this central tone. It's the feeling that a piece has a distinct key, such as C major or A minor. Music with tonality usually sounds 'resolved' or 'complete.' Tonality gives music a sense of direction and purpose, making it easy to follow and understand.
