 There are also musical saws with 3–4 octaves range, and new improvements have resulted in as much as 5 octaves note range.Two-person saws, also called "misery whips", can also be played, though with less virtuosity, and they produce an octave or less of range.Most sawists use cello or violin bows, using violin rosin, but some may use improvised home-made bows, such as a wooden dowel.
