A cellist is a musician who plays the cello, a string instrument that is larger than a violin and smaller than a double bass. The cello has four strings and is played by drawing a bow across the strings or plucking them with the fingers. It produces deep, rich tones and is commonly used in various music genres, including classical, jazz, and contemporary. Cellists often perform in orchestras, chamber music groups, or as soloists. They may also teach others how to play the cello. Famous cellists, such as Yo-Yo Ma and Jacqueline du Pré, have contributed significantly to the popularity and appreciation of the instrument.
