The term 'Instrument Played with a Bow' refers to three string instruments: the CELLO (5 letters), the VIOLA (5 letters), and the VIOL (4 letters). The CELLO is a large, bowed string instrument of the violin family, held between the knees of the seated player. The VIOLA is a bowed string instrument similar to the violin, but slightly larger and tuned a fifth lower. The VIOL is an early form of the violin, popular in the 16th and 17th centuries. All three instruments are played with a bow, and are used in classical music, jazz, and other genres.
