ABSTRACT:
One or more openings are provided through the tip sealing surface of a woodwind musical instrument mouthpiece to control and modify the boundary layer conditions between the reed and the tip sealing surface to improve ease of playing and the tonal characteristics of the mouthpiece. The openings may comprise a plurality of spaced circular apertures, or slots extending through the tip sealing surface, or a generally continuous elongated slot extending approximately the entire width of the tip sealing surface. The axis of the apertures or slots may be oriented to provide the desired operating characteristics.
