Melos Baroque Viola Tenor Viol Rosin is superb for use with period instruments using gut strings. This Baroque version rosin is stickier than rosin for their modern counterparts. Melos founder Christos Sykiotis, himself a cellist, explains it this way: “The gut string sounds not easy as a metallic string. We shouldn’t press the bow in order to play so we need a stickier rosin to play easy." Melos rosins are made in small batches from Greek pine resin and other natural ingredients.
