Abstract: In construction of a supporting mechanism for mounting a tubular tone generator to a stand of a percussive musical instrument, a holder shaft insertable into the sound generator is provided at its lower end with a pivotal lock bar of a biased mass distribution and a slidable coupled stopper to hold the lock bar at a prescribed angular position. When inserted into the sound generator, the lock bar turns automatically to assume the proscribed angular position due to the biased mass distribution and locks the holder shaft to the tone generator. Absence of the conventional tension wire binding system allows free choice in sound characteristics, simplified easy mounting operation and high mechanical durability even under vibratory conditions during performance.

Abstract: A musical instrument such as a jingle, a tambourine or a tomtom is provided with two or more hollow resonators arranged in the vicinity of at least one tone generator such as a pair of jingle discs or a head and preferably selectively closable by means of a slider coupled movably to the body of the instrument. Presence of a plurality of resonators, preferably different in resonance characteristics, assures colorful and rich resonance of tones generated by the tone generator and use of the slider enables easy and free finger control on the mode of resonance.
