Abstract:
1. A wind instrument, comprising: a head section having a proximal end, a distal end, a side surface and a bore extending therethrough; a mouth opening formed in the side surface of the head section, the mouth opening communicating with the head section bore and having a circumferential diameter, wherein the ratio of the head section bore diameter in the vicinity of the mouth opening and the mouth opening circumferential diameter is about 1.5 to 1 or less; a main section having a proximal end, a distal end, a bore extending therethrough and a plurality of toncholes communicating with the main section bore, wherein the main section bore diameter at the proximal end of the main section is greater than the head section bore diameter at the distal end of the head section; and an intermediate section having a proximal end, a distal end and a bore extending therethrough, the intermediate section bore having a first diameter at its proximal end substantially equal to the head section bore diameter at the distal end of the head section, a second diameter at its distal end substantially equal to the main section bore at the proximal end of the main section and a gradually increasing diameter extending from the proximal end to the distal end, whereby the proximal end of the intermediate section is coupled to the distal end of the head section and the distal end of the intermediate section is coupled to the proximal end of the main section, such that the head section bore, intermediate section bore and main section bore are coupled in flow communication.
