What are the SATB voice ranges and how do they contribute to the overall harmony of a choir performance?

The SATB voice ranges in a choir are Soprano, Alto, Tenor, and Bass. Each range contributes unique tones and harmonies to create a balanced and rich sound. Sopranos sing the highest notes, Altos provide a middle range, Tenors sing in a higher male range, and Basses sing the lowest notes. When combined, these ranges create a harmonious blend that adds depth and complexity to the choir performance.
