An impedance variator for limiting or suppressing the parasitic harmonics of a wind musical instrument, the impedance variator including at least one permanent magnet, the impedance variator including a brass tube intended to surround a substantially tubular or cylindrical portion of the wind instrument and the impedance variator including a manner for fastening the tube on the portion of the wind instrument.

A wind instrument bell includes a bell body and a ring. The bell body has a cylindrical shape, is configured to be connected to a wind instrument body, and has an outer circumferential surface having a recessed groove extending in a circumferential direction of the outer circumferential surface. The ring has a C shape, has a first end and a second end being separated from each other, and is accommodated in the recessed groove in a state of being deformed so that the first and second ends separate from each other.

Apparatus for enhancing tunes produced out of single-reed wind music instrument are disclosed. Apparatus comprise one or more sound enhancing elements in form of a plurality of elongated ribs or grooves, or one or more studs affixed to a reed's table side. Patterns of the elongated ribs/grooves can be straight or wavy lines orientated in longitudinal, transverse or oblique direction with respect to the reed. Each stud contains a three-dimensional (3-D) geometric shape portion for altering sounds produced out of a single-reed wind music instrument when played by a player, and a base of the 3-D geometric shape portion for affixing the stud to the table side of a reed in an area directly opposite to the heart of the reed. Dimensions of the area are single-reed wind music instrument dependent.

A ligature for a wind instrument is provided. The ligature includes a cord harness having a plurality of apertures extending transverse to a longitudinal axis of the cord harness, and an adjuster. The adjuster is connected to and extends transverse to the longitudinal axis of the cord harness. The ligature further includes a cord passing through the plurality of apertures in a spiral manner and engages a distal end of the adjuster.

A woodwind adaptor for woodwind musical instruments that enables a reed instrument to sound like an end-blown flute instrument. The woodwind adaptor replaces the standard reed-housing mouthpiece of the reed instrument with a recorder-style adaptor having a tone hole, whereby the tonal qualities through the reed instrument are, in part, propagated by the player's urged air stream over the edge of the tonal hole.
