Moderate viscosity: Do not think that the viscosity is as strong as possible. Rosin-type rosin is prone to noise, and changing the color tone is not easy. Especially rosin, it will quickly cake on the strings. On the one hand, agglomeration will directly affect the vibration of the strings, and the bowstring will also affect the bowstring.
The bite between the strings, in this case, some people will apply more rosin to increase the bite, which is actually counterproductive. At this point, as long as the rosin on the strings is cleaned, the rosin can be greatly improved. The bass is more viscous. If you use the rosin of the cello as a violin, you may find that the sound is getting louder and louder. Regardless of the size of the violin, some rosin can be used. Part of the rosin in order to increase the bite force, adding abrasive additives, such as gold powder, etc., some have no substantial help, but the metal composition may damage the finer paint surface.
2. Less dust: Sometimes we will find some musicians flying in the “smoke” when playing, in this case, in addition to excessive rosin, it may be due to additives. It usually happens on cheap, rough items. In addition to the health effects of dust, the scattering of rosin also makes it easy to kick the fingerboard and bow and kick, which affects the accuracy of the performance.
3. Durable: Rosin, the sound is very good after completion, but soon the rosin is "eaten" and must be added. Perhaps because of lack of stickiness or other reasons, too fast rosin is very troublesome.
Hard, light = low viscosity –> suitable for summer (wet heat) –> high music
Soft, dark = high viscosity –> suitable for winter (dry, cold) –> bass
