Gives a pure, clean and projecting sound that soloists love. It has the widest dynamic range and is particularly good for playing in large halls.Solo rosin provides powerful sound projection, yet it does not compromise on the sensitivity for the soloist. It is also very forgiving without the 'sound cracks' on the strings under a high amount of bow pressure. You will not be overpowered in the orchestra. You will feel the immediate change in your sound. Solo rosins were previously known under the names Paganini for violin, David for viola, and Casals for cello.
