Abstract: A wind instrument is constituted of a mouthpiece and a pipe structure including tapered/straight pipes. The pipe structure is constituted of a blow member and a branch pipe. The branch pipe is branched into a main pipe and an auxiliary pipe, which are straight pipes having openings and connected together in a branch shape. The blow member is connected to a branch point of the branch pipe. The branch pipe simulates resonance characteristic of a tapered pipe having a predetermined length, a predetermined distance between the upper base and the vertex, and a predetermined sectional area of the upper base commensurate with the sectional area of the main pipe.

Abstract: One exemplary embodiment of a flute comprises first and second chambers in which sound is resonated and a tonehole disposed at and shared by the first and second chambers. The tonehole is coverable by a single finger of an operator's hand and is configured to facilitate airflow communication from the first chamber through the tonehole and airflow communication from the second chamber through the tonehole. An exemplary embodiment of an ocarina comprises an instrument body having a first chamber having a first airway through which air is received and a second chamber having a second airway through which air is received, a top cover disposed on the instrument body, an upper tonehole disposed through the top cover to facilitate airflow through the first chamber and airflow through the second chamber, and a bottom cover disposed on the instrument body.

Abstract: A contrabassoon has a body, a tuning slide, a bocal pipe and a novel register system. The body, tuning slide and bocal pipe form a tube having a continuous bore. The register system comprises 5 vent holes formed in the tube. Key mechanisms for selectively opening and closing the vent holes are described. The contrabassoon further comprises linkage to selectively operate a low E vent pad, and an alternative C-sharp tone hole, with accompanying key mechanism.

Abstract: The present invention is directed towards an improved piccolo. The present invention incorporates several innovative design features that collectively enhance the sound and notes produced by the piccolo and also eases the playing transition between the piccolo and other instruments such as the flute. The present invention features a piccolo having an enlarged cylindrical-bore main body section and an enlarged conical bore headjoint section, enlarged toneholes for better ventilation and intonation, and an improved thumb key mechanism and other mechanisms for attaining notes of a heretofore unattainable tone quality, as well as a footjoint section which extends the lower range of the piccolo by three notes.

Abstract: The disclosed panpipe has adjustable plug means for closing and sealing the otherwise open tube bottoms at adjustable distances from the open tube tops, for tuning the panpipe tubes. The plug means includes a plunger seal fitted inside the tube, a manual adjustor rotatably mounted at the bottom of the tube, and threaded means connecting the plunger seal and manual adjustor together. Rotation of the manual adjustor finely shifts the axial position of the plunger seal in the tube. The plunger seal has a flexible sealing ring that can be loosened to slide freely within the tube, and that can be tightened to radially deform sealingly and mechanically against the tube inside. Means accessible via the open tube tops allow each threaded member to be manually rotated from the exterior of its tube, to tighten or loosen the associated sealing ring and set or release the plunger seal as adjusted axially relative to the tube.

Abstract: A musical instrument combining a modified portion of a tenor saxophone with a modified portion of a soprano saxophone joined together by means of a bracket whereby one of the two instruments can be moved relative to the other to obtain proper alignment whereby the two instruments can be played simultaneously. Each of the two instruments is provided with its own mouthpiece whereby a musician may play two notes simultaneously. Each instrument is also fitted with a trumpet bell outlet.
