Abstract
An improved mouthpiece reed holder system for single-reed woodwind instruments. The mouthpiece window is nearly the full length of the reed such that preferably 65% or more of the area of the underside of the reed is open to the tone chamber. The associated reed holder (commonly termed the ligature) clamps the reed to the mouthpiece along the lateral edges of the reed. The tone chamber of the mouthpiece is preferably the same length as the window, and preferably rectangular or square in cross-section throughout its length. A hollow spoon shaped cavity communicates with the bore and the tone chamber and merges the bore with the tone chamber.
