Everyone has a different vocal ability, but, on the average:

* Basses should be able to sing low E to G above middle C.
* Baritones should be able to sing low G to B natural just below the Tenor high C.
* Tenors should be able to sing C (below middle C) to E above high C.
* Altos should be able to sing low C (below middle C) to high C.
* Mezzo-Sopranos should be able to sing G (below middle C) to Eb above high C.
* Sopranos should be able to sing G (below middle C) to F above high C.

All voices should be able to maintain a connected, speech-level production of tone throughout their entire range.
