Although much research has been completed on finding features for instrument recognition system, little work has focused on the violin's timbre space. Suitable features from which a computer can assess the quality of a violinist's playing have been sought and the classification of violin note sound quality is investigated in this paper. The eventual outcome of this work can be applied in various systems including the development of a violin or bowed string instrument teaching aid, in automatic music transcription and information retrieval or classification systems.
