ABSTRACT:
In a flute mouthpiece in which the inner surface of a hole on this side, on which the lip is to be placed, is made to extend downward into a head pipe to form, on the inner wall of said head pipe, a projecting tongue, the lower surface of which is formed by a concave curved surface and in which the interior space of said head pipe is divided into two parts including an acoustic space and a fluid space, a concave portion having a cross-sectional area equal to that of said projecting tongue is provided on the lower portion of said inner surface of said head pipe which is continuous to said concave curved surface, so that the straight travel property of a sound is enhanced by an interference of a sound wave and the efficiency of exhalation converting its energy to a sound is enhanced, thereby making it possible to obtain a clear, vigorous, and rich quality sound. In addition, since the high-pitched tones of the scale of the flute cannot possibly be not true and a sound cannot possibly be confined inside, a sufficiently clear, vigorous, rich, and loud quality sound can be obtained.
