To grip the beam.
That is the rosinbag. Rosin is a substance (i don't know what), but it's white and powdery and it helps with grip. You see gymnasts rubbing it on their hands right before they do the paralell bars.
A rosin bag is designed to keep your hands tacky so you have plenty of grip on the ball in baseball.
A main use for rosin is to put it on a violin bow before playing, which gives the bow grip.
A violin, a bow, rosin, a case and a cloth to wipe the rosin off of the strings before you put it away.

No. Bow rosin is bow rosin.
Community Answer 1If you have not used the rosin on your bow before, take a nail file and file the top of the rosin down so that it looks a bit scratchy. Then run the scratchy side of the rosin up and down the horsehair of the bow in long even strokes. You know you have enough rosin on your bow when you draw the bow across the string and it leaves a white rosin trace. Remember to wipe off your strings with a towel when you're done playing to keep the rosin from building up. When applying rosin to the string do not touch the horsehair with your hand because the oils from your hand will ruin the horsehair if you touch it too much.______________________________Community Answer 2Only poor quality or old rosin needs to be scratched before use. I would recommend that having a clear tone tells you when you have enough rosin, if you go as far as leaving rosin dust on the string, you definitely have enough.
