An SSAA choir is a choir composed of two distinct Soprano sections and two distinct Alto sections. In an SSAA choir, First Sopranos sing the highest musical line, followed by Second Sopranos, First Altos, and Second Altos on the lowest line. First sopranos typically have the melody, with second sopranos and altos in harmonies. Women's choirs frequently sing a mixture of SSA and SSAA songs, and in order to create optimal balance, voices may be divided differently in an SSAA arrangement. Some mezzo-sopranos will sing the First Alto line.
