Four-part harmony refers to a musical arrangement or composition that involves four individual vocal or instrumental parts, each with its own melodic line. These four parts are typically written to be sung or played simultaneously, creating a rich and harmonically balanced sound.
In traditional Western music, four-part harmony commonly refers to the combination of four voices: soprano, alto, tenor, and bass. Each voice has its own range and specific role within the harmony.
The soprano voice is the highest, typically sung by female vocalists or played by instruments like the flute or violin. The alto voice is lower than the soprano and is often sung by female vocalists or played by instruments such as the viola.
