To simplify a structure and also reduce costs by making it possible to standardize reeds among different sound generation pitches.

Each reed structure body RAS is structured by fixing a base end part 3a of the reed 3 by a base cap 1 and a base 2, and fitting a red head RH1 to the tip part 3c of the reed 3. The reed 3 is set uniform in width a and thickness t over the whole length, and is formed in a same structure including the whole length for all pitches. A sound generation pitch of each reed 3 is determined by a choice of one reed from three kinds of reed heads RH1 with different mass and a projected length Lnet. The reed head RH1 is constituted of an attached part 10, a weight part 11, and an oscillation stopper 12. The weight part 11 is constituted of a high specific gravity resin, and can be tuned by fusion-processing the pitch adjusting part 11a with a laser beam.
