<P>PROBLEM TO BE SOLVED: To perform stable and accurate tuning even in a noisy place without being affected by outside noise. <P>SOLUTION: A tuner is installed in a stringed instrument body and a vibration detecting means of sensing acoustic vibration of the stringed instrument body when strings are twanged to produce a sound is installed in the resonance barrel of the stringed instrument body. Consequently, tuning can immediately be carried out and the vibration detecting means is installed in the resonance barrel in the stringed instrument body, so stable and accurate tuning can be performed even in a noisy place. <P>COPYRIGHT: (C)2004,JPO |
