I just started with violin.
I don`t understand the diferences between the dark and light rosin, when should they be used and how to tell that i used too much, or too little is there a proper / wrong way to apply rosin? Are there any guidelines or rules?

dark rosin is mainly for `deeper` string instruments (dbasses, cellos) its softer and has a more stickier residue, light rosin is mainly for violins and its harder. I try and use the light one in warmer weather and the dark one in normal-cold weather. A tip for when using the light rosin is to `break it up` by gently casting the frog of ur bow onto it to scratch it so more `chalk` comes out.It also depends on the type of strings u have, because i play antiques most of the time, they usually have eithr synthetic/ gut strings so theyd need softer/darker rosin, with the modern violins that are steel, they use light/hard rosin. with the frequency of applyng your rosin, i basically apply it jst a bit before playing, then re apply it while playing if the sound go too `scratchy` or `mute`, you`d really have to listen to your violin to know if the bow needs it.

Help that was any help
