Tone-altering apparatus and method for musical wind instruments

A method of ergonomic altering the tone within a musical wind instrument comprising the steps of:

• providing a musical wind instrument having a mouthpiece defining an entrance aperture, having a barrel defining a plurality of tone holes, an inner barrel surface defining a barrel bore, and an outer barrel surface opposing the inner barrel surface, having a foot portion defining an outlet aperture fluidly coupled to the barrel bore and the entrance aperture, and having an instrument length separating the entrance aperture and the outlet aperture;
• providing a simulated tone hole generating a simulated tonal frequency disposed a simulated tone hole length away from the entrance aperture;
• and
• affixing a chimney member to the barrel, wherein the chimney member includes an upper chimney surface defining an upper enclosed aperture disposed a chimney member length away from the entrance aperture, a chimney sidewall extending through one of the plurality of tone holes, only partially within the barrel bore, and defining a tone-altering channel, a lower chimney surface disposed in the barrel bore, defining a lower enclosed aperture, and disposed an offset length from the inner barrel surface, the lower enclosed aperture and the upper enclosed aperture separating the tone-altering channel and the tone-altering channel generating a chimney tonal frequency substantially equal to the simulated tonal frequency and the chimney member length is less than the simulated tone hole length.
