What clef does the play in?

Answer 1

The piano uses both the Treble clef (for higher pitches) and the Bass clef (for lower pitches). It plays in the key of C. Sometimes it is misinterpreted that the Treble clef is for the rigth hand and the Bass clef if for the left hand. This isn't true. Both hands can use the Treble clef or Bass clef, or even the right hand can use the Bass clef and the left hand can use the Treble clef.
