What is Tenormin? Tenormin (atenolol) is a beta-blocker that affects the heart and circulation (blood flow through arteries and veins). Tenormin is used to treat angina (chest pain) and hypertension (high blood pressure). Tenormin is also used to lower the risk of death after a heart attack.
The vocal tenor clef is used in vocal music for the male tenor voice part to indicate that the tenor voice actually sounds an octave lower that where it is notated in the normal treble clef. The vocal tenor clef should not be confused with the C clef that is also named tenor clef. In the past, the C clef known as the tenor clef was used for the tenor voice and is still used for other instruments in the same range such as the trombone, the cello, and the bassoon.
