How do you make sound come out of a violin?
The violin bow can only make the strings sound, when there is enough friction between the string and the bowhair. In order to achieve this, the bow is rubbed with rosin. Rosin is an amber-coloured tree resin, which is usually obtained from pine, spruce pine, spruce or larch.
Why is no sound coming from my violin?
New violin bows often do not produce any sound because they need rosin. Rosin is extremely important because it provides the bow hair with friction in order to produce a sound when the bow is pulled across the violin strings. ... Rosin comes in hard, round or oblong "cakes" of resin.
