The cello is a type of string instrument. It is part of the violin family and is known for its rich, deep sound, which is produced by vibrating strings. The cello is played in an upright position, resting between the player's knees, and is typically held with a bow, although it can also be played using pizzicato techniques (plucking the strings). Its range encompasses higher notes like those of the viola and lower tones that resonate like those of the double bass. The cello is prominent in various musical genres, including classical, jazz, and contemporary music, often contributing to orchestras and chamber ensembles.
