1 Playing violin will not go by itself you know! As they say practice makes perfect. You don't have to practice an hour at once, just start with 15 minutes a day, and if you can keep up the good work, you can increase the practice time a bit every week or so.  Breaking up your practice is helpful.
Rub the rosin cake slowly along the hairs of the violin bow repeatedly for five to 10 minutes if this is a new instrument and the first rosin application. Rub the rosin cake slowly up and down the bow three to five times if you have already used the bow, and it only needs a reapplication of rosin. Test the bow on the violin strings to see if it needs more to less rosin. When the level of rosin is perfect, you will hear a clear, clean sounding note.
