  • Patent number: 5192821
    Abstract: A mouthpiece is disclosed for use with a single-reed woodwind instrument such as a clarinet or saxophone. The mouthpiece has a unique reed holding assembly which includes a slot for constraining lateral movement of a reed and facilitating its longitudinal positioning. The reed is held in place by a holding device that includes at least one resilient band seated in at least one locating groove formed about the circumference and disposed in a central region along the mouthpiece. In a preferred embodiment, the mouthpiece includes a chamber and proximal portion which are constructed of two distinct materials with different acoustical resonance properties, thereby providing improved tonal and acoustic performance. In the embodiment for use with a clarinet, the chamber portion includes clarinet sealing rings for forming a durable and tight seal with the barrel of the clarinet.
