The answer to "Violin bow application NYT" is **rosin**. Rosin is a solid or semisolid viscous substance obtained either as exudations from certain plants or prepared by polymerization of simple molecules. It is used on the hair of violin bows to increase friction and help the bow grip the strings.
Rosin is applied to the bow by rubbing it with the hair of the bow. The amount of rosin applied depends on the humidity and temperature of the environment. Too much rosin can cause a harsh sound while too little can cause a weak sound.
