<p>PROBLEM TO BE SOLVED: To give fullness and advanced fusion with other musical instruments to musical sounds in blowing of a wind instrument, by sufficiently improving harmonic overtones in musical sounds. SOLUTION: At least one sloped partition 22 having at least one guide surface 24 is provided in the inside 21 of the tubular body of the head joint 20 of the wind instrument. When the sloped partition and the guide surface perform automatic guidance, and thereby, the resonant path of the blowing air flow increases, gas molecules create abundant waves of expansion in a given amount of time. As a result, the kinetic energy of the internal air flow of the tubular body of the wind instrument or the head joint is automatically balanced in the tubular body of the head joint.</p> |
