10bis 11 New type structure of Boehm system clarinet to transpose 10bis key and 11 key

摘要

PURPOSE: A boehm system clarinet is provided to shorten time required for converting into a preliminary action after pressing keys, while achieving stability of sound and efficiency of play. CONSTITUTION: A boehm system clarinet comprises a 10 bis key(102) and a 11 key(101) integrated into a single unit; and axial supports(201,203) for 10 bis key and 11 key, which are arranged above a 10 key pad(106). A keyboard ranging in the central axis between the 10 bis key pad and a 11 key pad(105), is bent into a circle. The 10 bis key and the 11 key are arranged in the left side of the clarinet, and two keys are arranged slightly above a 10 key. The 10 bis key and 11 key are arranged higher than the 10 key, when the clarinet is laid down on a floor.
