As a darker rosin with a slightly softer constitution than many alternatives, ABs Cello Rosin recipe is a little softer than its violin counterpart as it is designed to deliver good levels of smooth traction on the larger strings of a cello with a medium-rated Grip Profile of 5 (GPR#5). Therefore, AB rosin can be chosen by any standard of musician but can be considered perfectly suitable for beginners up to early conservatoire players.
