Four-Part Harmony

Four-part harmony is a musical technique where a piece is composed or arranged using four independent yet harmonically interconnected voices: soprano (high), alto (mid-high), tenor (mid-low), and bass (low). Each voice moves separately but together they create a rich, balanced sound typical of Western choral and classical music. The voices work within specific rules to ensure smooth transitions and pleasing consonance, often following patterns of chord progressions. This method provides depth, stability, and a sense of fullness, allowing multiple melodies to interweave harmoniously while maintaining clarity and structure.
