ABSTRACT:
A mouth-pipe of a saxophone is disclosed. A mouth-pipe is covered on a top of a saxophone wind tube. A high pitch hole is installed on the upper end of the mouth-pipe which is pivotally installed with an octave key. A key cover is installed at the inner surface of the upper end of the octave key, and the key cover presses against the high pitch hole of the mouth-pipe. A ring is formed at the lower end of the octave key. A push rod connected to a high pitch key is installed above the saxophone wind tube. If the high pitch key does not press the high pitch hole, a high pitch is emitted; while if the high pitch key is released, a low pitch is emitted; Two long ear seats facing with one another are installed at the pivotal position of the octave key, and a convex point is formed at a lower end of each long ear seat. Two opposite long pivotal seats are placed at the pivotal positions of the mouth-pipe. The outer surface of each long pivotal seat is placed against the inner surface of the respective long ear seat so that the octave key oscillates steadily upwards and downwards, thus the key cover at the upper end of the octave key accurately covers the high pitch hole of the mouth-pipe and the convex point at the lower portion of the long ear seat resists against the mouth-pipe of the long pivotal seat for positioning the opening of key cover at the upper end of the octave key. Therefore, a high pitch is emitted accurately.
