Mouthpiece for woodwind instruments

There is disclosed an improved mouthpiece intended for woodwind instruments such as clarinets and saxophones, of the type generally known, which further includes as an improvement a key-shaped slotted cut-out section formed along the horizontally flattened portion thereof, the key-shaped slotted cut-out section formed by a pair of opposed curvilinear flanges formed along the opposed side edges of the slotted cut-out section, the curvilinear flanges having a sufficient thickness such as to reduce the overall diameter of the wind channel by between 25% and 50% thereof, thereby to create a wind compression chamber adjacent to the tip end of the mouthpiece along the path of the wind channel thereby to function to smooth out the vibrational air pulses as the same travel through the mouthpiece and into the instrument in order to improve the tonal qualities of the instrument throughout the entire tonal range of the instrument.
