大提琴 樂譜
The violoncello (or cello) is an instrument from the violin family. It has four strings tuned in perfect fifths. It became popular in the first decades of the 18th century, eventually replacing the bass violin and other mid-sized similar bowed chordophones. Nowadays the can be found in orchestras or a solo instrument, and less frequently in some modern ensembles, including rock bands. Music for the cello is usually written in the bass clef, but both tenor and treble clefs are used for high passages.
