One of the most valuable things when learning to play an instrument or when refining one's playing technique is the precise advice of an experienced teacher. There are, however, aspects of the musician's interaction with the instrument which are nearly impossible to tell from looking at it. One of them is force. Yet, force is fundamental in playing an instrument.

QuantiForce by Bonsai Systems^® is the world's first device that immediately displays the relevant forces that are applied onto the instrument while playing. It provides the missing objective information for giving precise advices during teaching and serves as a tool giving instantaneous visual feedback when practicing at home.

QuantiForce is now available for most brass and stringed instruments in variants that are suitable for beginners, professional musicians, teachers, as well as researchers. See below for details.
