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.
Claims19
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.
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.
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.
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.
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.
