About CelloThe cello ( CHEL-oh; plural cellos or celli) or violoncello ( VY-ə-lən-CHEL-oh; Italian pronunciation: [vjolonˈtʃɛllo]) is a string instrument. It is played by bowing or plucking its four strings, which are usually tuned in perfect fifths an octave lower than the viola: from low to high, C2, G2, D3 and A3. It is the bass member of the violin family, which also includes the violin, viola and the double bass, which doubles the bass line an octave lower than the cello in much of the orchestral repertoire. After the double bass, it is the second-largest and second lowest (in pitch) bowed string instrument in the modern symphony orchestra. The cello is used as a solo instrument, as well as in chamber music ensembles (e.g., string quartet), string orchestras, as a member of the string section of symphony orchestras, most modern Chinese orchestras, and some types of rock bands.
