Automatic Discovery of Right Hand Fingering in Guitar Accompaniment

The analysis of musical interpretation, an important research topic in Computer Music, is usually focused on the study of musical dimensions like harmony and melody for piano music. Despite its obvious importance in expressive performance, rhythm is somewhat neglected as well as guitar music. This paper introduces a novel algorithm for the automatic discovery of right hand fingering in guitar accompaniment. This algorithm introduces the notion of hand position and uses the idea of minimizing the costs associated to each transition between hand positions as its basis. The tests we made showed that it correctly fingers all examples we used.
