ABSTRACT:
A musical wind instrument of the type in which the pitch of the note to be produced is initially created by a person blowing the instrument, the instrument being provided with at least one elongated tubular section forming a sound path with two ends. This section has twelve segments arranged in tandem, the length and diameter of each segment being progressively greater in the direction the sound travels through the section. The length of each segment corresponds to the wave length of a different note of a chromatic scale. In addition, the boundary between adjacent segments is formed by an abrupt change in diameter and the boundary between adjacent segments is made from a softer metal than the segment walls themselves.
