Vocal range More important than range in voice classification is tessitura, or where the voice is most comfortable singing, and vocal timbre, or the characteristic sound of the singing voice. For example, a female singer may have a vocal range that encompasses the high notes of a mezzo-soprano and the low notes of a soprano. A voice teacher would therefore look to see whether the singer were more comfortable singing higher, or lower. If the singer were more comfortable singing higher, then the teacher would probably classify her as a soprano. The teacher would also consider the sound of the voice; sopranos
Bass (voice type) Bass (voice type) A bass ( ) is a type of classical male singing voice and has the lowest vocal range of all voice types. According to "The New Grove Dictionary of Opera", a bass is typically classified as having a vocal range extending from around the second E below middle C to the E above middle C (i.e., E–E). Its tessitura, or comfortable range, is normally defined by the outermost lines of the bass clef. Categories of bass voices vary according to national style and classification system. Italians favour subdividing basses into the "basso cantante" (singing bass), "basso buffo"
