A male singer is a person who sings using their vocal cords. There are four main categories of male singers: TENOR, BARITONE, BASS, and ALTO. Tenors are known for their high-pitched voices and are often used in operas and musicals. Baritones have a lower range than tenors and are often used in jazz and blues music. Basses have the lowest range of all male singers and are often used in classical music. Altos are the rarest type of male singer and have a higher range than baritones.
