Definition of C clef in English:
The soprano, alto, or tenor clef.
- Instruments with ranges that do not fall comfortably into either bass or treble clef may use a C clef or may be transposing instruments.
- For some teen and adult students of an abstract bent, you might mention C clefs, and even treble and bass clefs which move around and why.
- The C clefs tend to be used much less commonly, especially in jazz, although the tenor clef is sometimes read by trombonists.
