The tenor clef is a specific clef used in sheet music, primarily utilized by instruments such as the viola, cello, and bassoon. Though it is often referred to as the tenor clef, it is also commonly known as the C clef or the viola clef. This is because it indicates that the note at the center of the symbol is middle C, consequently specifying the suitable position to read the other notes in the score. Additionally, the tenor clef is occasionally known as the Baritone clef, the French clef, or the Mezzo-Soprano clef. Whatever it is called, this clef is an essential component of any sheet music intended for the instruments that use it.
