ETYM French clef key, a key in music, from Latin clavis key. Related to Clavicle.
A musical notation written on a staff indicating the pitch of the notes following it.
In music, a symbol prefixed to a five-line stave indicating the pitch range to which the written notes apply. Introduced as a visual aid in plainchant notation, it is based on the letter G (treble clef), establishing middle C (C4) as a prime reference pitch, G4 a fifth higher for higher voices, and F3 a fifth lower for lower voices.
The C clef is now comparatively rare, except for viola, cello, and bassoon; for most other instruments the G and F clefs are standard. + prikaži više
