Liebenzeller Silver creates a softer, warmer, more enveloping sound, especially at high frequencies. It enables fine nuances and subtlety. The bow can be guided smoothly, especially in pianissimo. The Silver rosin should definitely be considered for Baroque playing.
Silver I for violin/viola: warm and balanced, offering enhanced clarity
Silver II for violin/viola: slightly softer, smoothing out any rough edges
