Abstract: A wind instrument cavity resonator and optional flexible flute crown assembly capable of improved sound generation and amplification within a flute or piccolo body is presented. The crown presents a swiveling nut joint, and the resonator has one or more counterweights to assist in the sound and weight balancing of the musical instrument, creating an acoustically pleasing flute or similar sound generation device.

Abstract: A flute stopper having at least one sealing means able to seal the musical cavity and translation means to adjust the positioning of said seal. Said flute stopper is designed to be capable of interfacing with the original factory screw, nut and crown via nuts and/or fittings, including either compression or NPT fittings. Both or either end of said plug may be tapered to facilitate said interfacing.

Abstract: A musical instrument ligature having at least one compression bed which act as the contact points between the ligature and the reed on the mouthpiece of a wind instrument. Said ligature is significantly juxtaposed to an opposite spar and support elements, positioned so as to optimize the fixation of the reed to the mouthpiece.
