The soprano is the highest female voice type. Sopranos are typically divided into two categories: lyric sopranos and dramatic sopranos. Lyric sopranos have a light, clear voice and are often used for singing delicate, romantic roles. Dramatic sopranos have a more powerful, resonant voice and are often used for singing more dramatic roles.
Mezzo-soprano
The mezzo-soprano is the middle female voice type. Mezzo-sopranos have a voice that is darker and richer than that of a soprano, but not as heavy as that of a contralto. Mezzo-sopranos are often used for singing character roles or roles that require a strong, flexible voice.
Contralto
The contralto is the lowest female voice type. Contraltos have a dark, rich voice that is often used for singing supporting roles or roles that require a strong, low register.
Tenor
The tenor is the highest male voice type. Tenors are typically divided into two categories: lyric tenors and dramatic tenors. Lyric tenors have a light, clear voice and are often used for singing delicate, romantic roles. Dramatic tenors have a more powerful, resonant voice and are often used for singing more dramatic roles.
Baritone
The baritone is the middle male voice type. Baritones have a voice that is darker and richer than that of a tenor, but not as heavy as that of a bass. Baritones are often used for singing character roles or roles that require a strong, flexible voice.
Bass
The bass is the lowest male voice type. Basses have a dark, rich voice that is often used for singing supporting roles or roles that require a strong, low register.
