This so far is an excellent product that, being a dark rosin, may be best for the winter months and/or cellos. Maybe it will work for humid climate violin too? The round rosin cake format is nice because it avoids hair breakage and also wastage *if* you use it properly. This means rotating it to all angles evenly rather than just digging a gutter into it on one angle every time, which guarantees you waste half of the cake carelessly. You can roll the bow a bit to ensure even coverage on all exposed hair surfaces. This rosin needed no sanding or scoring to start working, it went on immediately even though shiny. I don’t recommend doing anythin special to prepare it for use. What you are trying to do with rosin and your bowing in general is to have loud, rich tones with strong fundamental frequency, smooth, warm attacks unless you really dig in to bite the string, and no hitches or scritches even on fortissimo double stops down near the frog. The naïf or ignorant teacher may try to explain the latter as simply a symptom of poor bowing technique; but I’ve found bows can be made more or less immune to hitches and scritches by removing any bad, over-sticky rosin (by playing it out or cleaning with denatured alcohol) and playing-in the hairs themselves to avoid any rough patches that induce the ugly turbulence. Because that process sounds simply dreadful, use both a mute and hearing protection to do it. I haven’t broken many hairs doing that. Also, one needs to clean off the rosin buildup on the strings frequently, I find kimwipes the best to do this. Better rosin will be more immune to these effects, and importantly, less rosin should be applied to the frog end of the hair, as excess pressure is easily applied there and that area doesn’t need much help being loud. I wince when I see people scrubbing extra rosin into the frog area: why are you doing that? Probably just something that hasn’t been countered with enough science. Or you could ignore all that advice and just focus on bowing technique so perfect you can sound smooth even with a horrible bow. If I was in the business of selling lessons, not to mention expensive bows and rehairings, I might encourage that level of ignorance. But following this program I’ve made cheap student bows sound nice even if their balance and bounce won’t ever be terrific.
