About Cello
The cello ( CHEL-oh; plural celli or cellos) or violoncello ( VY-ə-lən-CHEL-oh; Italian pronunciation: [vjolonˈtʃɛllo]) is a bowed (and occasionally plucked) string instrument of the violin family. Its four strings are usually tuned in perfect fifths: from low to high, C2, G2, D3 and A3. Each string is an octave lower than the viola's four strings. 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.
