ギター演奏熟達度評価のための各弦独立型ピックアップの開発

抄録

Many researches on musical instrument performance mastery support have been researched, and there were some methods to assist a beginner using visual, auditorial, and haptic assist. However the evaluation method has not been established. Therefore, this paper develops a pickup for independently observing vibrations of each string in the guitar performance and evaluates it. The pickup contains a piezo element for measuring the vibration of each string, and the key of the sound is searched through a filter circuit. In the experiment, the strings were equally suppressed, and picking all the strings at once. As a result, the vibration of each string was able to be distinguished with accuracy of 94.6% at all strings vibration.
