Violin family

Both the violin and viola are played under the jaw. The viola, being the larger of the two instruments, has a playing range that reaches a perfect fifth below the violin's. The cello is played sitting down with the instrument between the knees, and its playing range reaches an octave below the viola's. The double bass is played standing or sitting on a stool, with a range that typically reaches a minor sixth, an octave or a ninth below the cello's.
