If 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.

Only 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.
simply rub the rosin up and down the bow.
No. Bow rosin is bow rosin.
You basically rub the hairs of the bow onto the rosin. But, the rosin has to be scraped to gab onto the bow hairs. But good rosin does no need to be scraped before using. I one bought a violin that came with a free rosin and I rubbed it on for half an hour and nothing went on. I then bought a more expensive piece of rosin and it worked just fine.
Do you mean rosin? To rosin the bow, you get some rosin from your music store, and rub it along the bow hairs a couple of times.
A main use for rosin is to put it on a violin bow before playing, which gives the bow grip.
depends on what you bargain for. Normally: violin, bow, case and maybe rosin
A violin, a bow, rosin, a case and a cloth to wipe the rosin off of the strings before you put it away.
No. Use rosin to care for the bow, not wax.
If you mean the rosin, you take the rosin in your left hand and you move it up and down the bow hair.
You use rosin (resin is what comes out of the tree in it's raw state), on bows (this goes for violin, viola, cello, and bass bows) so that the bow can get a good grip on the strings and make a sound. New bows will need to be rosined a good amount because it hasn't been played yet and rosin hasn't taken a hold on the bow hairs yet. A bow that has been used before and been played for a while doesn't need as much rosin as a new bow because there is already rosin on the bow hairs. If you don't rosin your bow every once in a while, the sound that will be produced will sound wierd.
It vibrates the string by pulling it across the string. The hair on the bow has rosin applied to it making it sticky.
It sounds like you are referring to "rosin".
Occasionally. If it is used once, that's fine. But, cello rosin has more grit than violin rosin because the cello's strings are thicker. If a violinist used cello rosin (instead of violin), the bow hair will become very gritty and you may need to get a rehair.
