who sing the tenor voices
Bob, Eli Manning and Santa
In general first tenor is higher but the parts can cross over sometimes.
A bari tenor is a baritone who has a tenor extension... for instance singing c5 a.k.a tenor C! FALSETTO doesnt count!
No, the tenor horn is from the trumpet/brass and the tenor sax is from the woodwind. They are also in different keys. The tenor horn is in Eb like the alto sax.
