1. The method of producing controllable and alterable combinations of pitch and timbre in a free reed musical instrument, comprising the steps of:
- (a) causing a free reed to vibrate within a chamber of variable geometry and sound a tone with a prescribed combination of pitch and timbre; and
(b) connecting said free reed with an air passageway having a wall, a port in said wall and lid for said port; and
(c) transmitting motion from a key to said lid of said port;
thereby to modify said combination of pitch and timbre.

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.

8. Apparatus comprising
an instrument having a key attached to a selector valve for controlling the vibration of a free reed for producing a predetermined tone; -
a chamber of variable geometry associated with said free reed further including means for modifying said chamber to control the vibration of an air mass therein; a linkage connecting said chamber with said key whereby movement of said key causes a further tone that differs from said predetermined tone and is modified by the controlled vibration of said air mass, being provided by a second free reed that can co-vibrate with the first mentioned free reed; further including means for allowing said second free reed to vibrate without co-vibration of said first mentioned free reed. - View Dependent Claims (9, 10)

11. Apparatus comprising
an instrument having a key and a free reed for producing a predetermined tone; -
a chamber of variable geometry associated with said free reed; a linkage connecting said chamber with said key; whereby movement of said key causes a further tone that differs from said predetermined tone; further including means for modifying said variable geometry chamber to control the vibration of an air mass therein; whereby said second musical tone is modified by the controlled vibration of said air mass; said chamber being closed except for a first opening of predetermined size leading to said free reed through a passageway, and a predetermined number of additional openings, with each additional opening sized to produce said second musical tone. - View Dependent Claims (12)

13. The method of producing controllable and alterable combinations of pitch and timbre in a free reed musical instrument, comprising the steps of:
-
(a) causing a free reed to vibrate and sound a tone with a prescribed combination of pitch and timbre; and (b) connecting said free reed with an air passageway having a wall, a port in said wall and lid for said port; and (c) transmitting motion from a key to said lid of said port; thereby to modify said combination of pitch and timbre; further including the step of enclosing said air passageway except for a predetermined number of openings, with a first opening leading to said reed and a second opening identified with said port.

14. Apparatus comprising
an instrument having a key and a free reed for producing a predetermined tone; -
a chamber of variable geometry containing said free reed; and a linkage connecting said chamber with said key; whereby movement of said key causes a further tone that differs from said predetermined tone; wherein said linkage provides a predetermined number of movement regimes for said key, including; a regime in which one movement of said key is accompanied by a predetermined tone; and an additional regime in which a different movement of said key is accompanied by said further tone. - View Dependent Claims (15, 16, 17, 18, 19)
