Alto is properly the term for the second top part in four-part mixed-voice vocal writing. Applied to voices it means no more than can muddle their way through the alto part, which is not saying a whole lot, because the alto part is notoriously mind numbing (not that itâs not an essential part of the whole, or that weâre not grateful for the people who deal with it).
