how many horse hairs are on a violin bow
Bow (music) A bow maker or archetier typically uses between 150 and 200 hairs [4] from the tail of a horse for a violin bow. Bows for other members of the violin family typically have a wider ribbon, using more hairs. There is a widely held belief among string players, neither proven nor disproven scientifically, that white hair produces a "smoother" sound and black hair (used mainly for double bass bows) is coarser and thus produces a "rougher" sound. Lower quality (inexpensive) bows often use nylon or synthetic hair. Rosin, or colophony, a hard, sticky substance made from resin (sometimes mixed with wax), is regularly applied to the bow hair to increase friction.

Air on the G String The arrangement differs from the original in that the part of the first violins is transposed down so that it can be played entirely on a violin's lowest string, i.e., the G string. It is played by a single violin (instead of by the first violins as a group).
