Disclosed is a new-type native American flute with a new finger hole design. One end of a flute head is provided with a mouthpiece, and the other end of the flute head is connected with a flute body. The front of the flute head is provided with a flute nose and a sound outlet. The flute body is provided with 7-10 finger holes. The finger holes may include main finger holes and an auxiliary finger hole, and the auxiliary finger hole is on the side of the main finger holes. The main finger holes include front main finger holes and a back main finger hole. Arranging an auxiliary finger hole on the surface of a native American flute in the present disclosure may broaden the range, increase altered tones as well, and further realize fine tuning for the altered tones.

A predetermined sound interval interlocking mechanism 7 for making opening and closing operations of sound hole covers 4 of an existing sound range interlock with opening and closing operations of sound hole covers 4 of an expanded sound range is provided and a sound hole switching mechanism capable of collectively closing the sound holes of the high-pitched range by one key operation is provided independent from the predetermined sound interval interlocking mechanism 7. By using the above described mechanisms, both ranges can be played only by the operation of selecting the sound range and operating the sound hole covers 4 of the existing sound range. In addition, a slide plate 9 sliding along an inner surface of the tube for forcibly opening and closing the sound holes 3 from the inside of the tube is proposed as the sound hole switching mechanism.

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 reed for a reed instrument, including a polyamide.

A tone-altering apparatus and method for musical wind instruments wherein the apparatus, used in combination with a musical wind instrument, comprises a chimney member with an upper chimney surface defining an upper enclosed aperture, with a chimney sidewall extending through one of a plurality of tone holes and defining a tone-altering channel, and with a lower chimney surface defining a lower enclosed aperture, the lower enclosed aperture and the upper enclosed aperture separating the tone-altering channel. The method of ergonomic altering the tone within a musical wind instrument comprises the steps of providing a musical wind instrument, providing a simulated tone hole generating a simulated tonal frequency, and affixing the chimney member to the barrel of the musical wind instrument to generate a chimney tonal frequency substantially equal to the simulated tonal frequency and provide a chimney member length less than the simulated tone hole length.

An ergonomic flute having a head joint that bends slightly downward and away from the user thereby reducing the muscular stress of holding the instrument for long periods of time is disclosed herein.
