 Music for the cello is generally written in the bass clef, with tenor clef and treble clef used for higher-range passages.Played by a "cellist" or "violoncellist", it enjoys a large solo repertoire with and without accompaniment, as well as numerous concerti.The cello often plays the bass part, both in chamber music such as string quartets and the orchestra's string section, where the cello may be reinforced an octave lower by the double basses.
