Natural dark rosin, the D'Addario dark rosin is a perfectly reasonable choice for a young instrumentalist. Darker rosin is typically a seasonal or instrument-based choice. If you play a high-stringed instrument like a violin or viola, you may want to try light rosin in the warmer months and dark rosin in the winter months. Dark rosin works fine when out of season or on a higher instrument but for the best sound quality, make your decision based on season or instrument type. The product comes in an easy-to-grip plastic channel that prevents rosin from making hands sticky. It is suitable for any kind of bow, synthetic or horsehair, whether or not you crush it. This all-natural rosin is manufactured in New York and is the perfect option for young musicians.
