The present invention relates to a device which is introduced into the window of the mouthpiece, between the mouthpiece and the bevel, and which allows the volume of the sound produced by the recorder to be reduced, slightly affecting the quality of the sounds produced by same.

A wind instrument includes a tube body; a tone hole tube that has an inner open end formed extending from the outer periphery of the tube body and opening to the inside of the tube body, and an outer open end opening to the outside of the tube body; and a finger pressing plate that, in the radial direction of the tone hole tube, extends from the outer open end of the tone hole tube to the outside of the tone hole tube.

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.

A mute equipment capable of controlling a breath pressure and reducing the volume of the sound during a performance state in normal manner, an adapter thereof and the wind instruments equipped with them, are characterized in that it the mute equipment capable of controlling a breath pressure is to be attached to the blowing section of the wind instruments, wherein the equipment has a hole to release the breath and a section of restricting a wind way width. The mute equipment capable of controlling a breath pressure may be further characterized in that the equipment has a section of adjusting a breath volume to adjust the size of the hole to release the breath. The mute equipment capable of controlling a breath pressure may be further characterized in that the section of adjusting a breath volume can use as the section of restricting the wind way width.

One embodiment of the present application sets forth a method for simulating an audio output of a three-dimensional object that includes a resonant cavity. The method includes receiving an input mesh of a three-dimensional shape and a hole configuration. The input mesh has an outer surface and an internal cavity, and the hole configuration includes one or more holes. The method further includes adding the one or more holes to the three-dimensional shape based on the hole configuration to generate a modified three-dimensional shape having a resonant cavity. The resonant cavity includes the one or more holes and the internal cavity. The method further includes determining an air pressure coefficient matrix for the resonant cavity. The method further includes computing a minimum non-zero eigenvalue for the air pressure coefficient matrix. The method further includes determining an output resonant frequency for the resonant cavity based on the minimum non-zero eigenvalue.

A musical instrument is disclosed which has a first tubular member having an inlet end and an outlet end, an interior surface, and an exterior surface, a second tubular member having an inlet end and a closed end having a one-way valve, the second tubular member adapted for receiving the first tubular member for moving the first tubular member relative to the second tubular member, and the second tubular member for receiving a liquid through the one-way valve, and a stopper having an opening, the stopper for being inserted in the inlet end of the second tubular member and the opening for receiving the first tubular member there through.

An apparatus comprises a flute, a base, and a thumb rest. The base is attached to the flute and defines a channel. The thumb rest is inserted into the channel and defines an elongate body. The thumb rest is positioned such that a flutist may rest a right thumb against the thumb rest while using conventional fingering to play the flute.
