Which voice part usually sings the highest in a four-part harmony setting?

In a four-part harmony setting, the soprano voice typically sings the highest. This is due to the traditional vocal arrangement found in choral music, where the soprano section is designated for higher female voices. The range of the soprano extends approximately from middle C (C4) to the high A (A5) or even higher, depending on the individual singer's capabilities.

In choral music, the parts are arranged so that the soprano voices carry the melody or the most prominent vocal line, supported by the lower harmony parts of alto, tenor, and bass. This structure allows for a balanced sound, with the sopranos reaching the highest pitches that provide bright, clear tones that often stand out in the texture of the music.

The other voice parts—alto, tenor, and bass—are composed of lower vocal ranges with altos generally singing in a range above the tenor but below the soprano, tenors typically covering a range that is higher than the bass but lower than the soprano and usually extending from about C3 to A4, and basses, which sing the lowest parts, generally range from E2 to E4. This arrangement highlights the role of the soprano as the highest voice in four-part
