The violin, viola, cello, and double bass make up the family of  bowed string instruments. The bow is usually made of horse tail  hair stretched over a wood frame, and rosin (a solid resin  extracted from pine trees) is applied to the hair so that it has  sufficient friction to vibrate the strings. Like the guitar and  harpsichord, the strings on bowed instruments can also be plucked.
