Abstract
Apparatus and methods for its use are provided that relate to an octave/register key for musical wind instruments that combines (i) a vent formed by alignment of an opening of a core and a sidewall aperture of a sleeve, wherein the core is slidably and coaxially mounted within the sleeve, or a vent formed by alignment of sidewall apertures on an inner chamber slidably mounted within an outer chamber, and (ii) the mechanism to open and close such a vent. The device, upon actuation, vents the wind instrument air column to remove the fundamental pitch frequency, and can be mounted anywhere on the body of a musical wind instrument or onto any existing tone hole key of the instrument.
