String players apply [[rosin]] to the bow hair so it "grips" the string and makes it vibrate. Double bass rosin is generally softer and stickier than violin rosin to allow the hair to grab the thicker strings better, but players use a wide variety of rosins that vary from quite hard (like violin rosin) to quite soft, depending on the weather, the humidity, and the preference of the player. The amount used generally depends on the type of music being performed as well as the personal preferences of the player. Some brands of rosin, such as Wiedoeft or Pop's double bass rosin, are softer and more prone to melting in hot weather.
