A clef is the symbol at the beginning of a staff that identifies a reference pitch. It gives the lines and spaces their note names, so the same position can mean different notes in different clefs.
Explore the G, C and F families, historical staff positions, octave variants, percussion and tablature. Each card shows the sign, its meaning and names in English, French, Italian and Arabic.
