Abstract:
    Improved performance and versatility of a free-reed instrument by linking a key of the instrument to a variable geometry chamber, which provides modifications in musical tones. The instrument can be an accordion or other free-reed instrument, and a passageway of the chamber is manipulated to alter the combined pitch and timbre of the tones.
