Viola Note Reading Practice
Viola is the instrument that most often uses alto clef, a C clef where the middle line is middle C. It uses treble clef for high passages. Alto clef looks unfamiliar at first because every note sits a step lower or higher than it would in treble or bass. With a little practice it becomes natural.
