A wind instrument having a tone color produced from sound producing reeds in response to the blowing of breath through a mouthpiece, is played by manipulating keys arranged to produce notes of the scale in the same manner as a conventional classical wind instrument such as a clarinet, saxophone, trumpet or french horn, as the case may be. The instrument is constructed with a main body of the wind instrument, a plurality of scale operations keys, air passageway change-over valves, a plurality of groups of sound producing members which produce tones in correspondence to finger action of the scale operation keys, and a mechanism for forming the air passageway to introduce air blown in from a mouthpiece of the wind instrument by the operations of a corresponding air passageway change-over valve into the corresponding sound producing member.
