The cello, short for violoncello, is a bowed string instrument with a rich, deep sound. It is a member of the violin family, larger than the violin and viola, but smaller than the double bass. The cello has four strings tuned to C, G, D, and A, and it is played while seated, with the instrument resting between the player’s knees and leaning against their shoulder. Its range is versatile, allowing it to produce both low, resonant bass notes and higher, melodic tones. The instrument’s body is made of wood, and its bow is traditionally strung with horsehair.
