| Outline of Final Research Achievements |
The purpose of this research is to develop a technique for predict the muscle activities from acoustic features (and vice versa) in playing the trumpet. We obtained the following results:
(1) The muscle activity is greater as the pitch is higher.
(2) In transforming the acoustic features extracted from the sound of playing the trumpet to muscle activity values, a non-linear method (neural network) is more accurate than a linear method (affine map).
