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.
English longbow The Battle of Flodden (1513) was "a landmark in the history of archery, as the last battle on English soil to be fought with the longbow as the principal weapon..."[58] The last recorded use of bows in an English battle may have been a skirmish at Bridgnorth, in October 1642, during the Civil War, when an impromptu town militia, armed with bows, proved effective against un-armoured musketeers.[59] The Battle of Tippermuir (1644), in Scotland, may have been the last battle involving the longbow.[60] Longbowmen remained a feature of the Royalist Army, but were not used by the Roundheads.
