Flute range widening method

Abstract

Provided is a flute range widening method. A sliding disk serves as a key part to realize range expansion, sleeves the upper side of the middle and right position of a cylinder body, and forms axial sliding cooperation with the upper side of the middle and right position of the cylinder body. A bass positioning recess through which the sliding disk translates leftwards to a bass band and thus positioned is formed in the left part of the lower front side of the middle and right position of the cylinder body, and a high pitch positioning recess through which the sliding disk translates rightwards to a high pitch band and thus positioned is formed in the right part of the lower front side of the middle and right position of the cylinder body. a reed ring extends out of the sliding disk between third and fourth sound holes at a position near to the front side of the fourth sound hole, and serves as an integrated structure for range-variable positioning operation and surrounding the cylinder body together with the sliding disk; the inner sides of the sliding disk and the reed ring surround the cylinder body; the front side of the reed ring corresponds to a connecting line position of the bass positioning recess and the high pitch positioning recess, and a positioning projection protruded to the cylinder body is prepared, and serves as a key structure for the range-variable positioning operation; and the positioning projection presses the cylinder body via an elastic force of the reed ring. Before play, the distance between the thumb and the little finger of a hand placed in front is relatively larger than usual, the thumb and the little finger do not make contact with the sliding disk of the sound hole, and the distance between the thumb and the little finger of the hand placed in the back is kept as usual.

Description

technical field [0001] The invention relates to a sound range expansion technology of a wind instrument-dizi. Background technique [0002] Dizi is a national wind instrument with a long history, which can express rich timbres and play beautiful music. However, due to its material and structural factors, it is difficult to achieve a wider playing range. Existing method is nothing more than to be equipped with flutes of different modes, and to change performances; But this method is all owing to needing a period of changing time, only is suitable for the program of the big tune section of the same tune, the long break of the different tone, can not accomplish the program of continuously changing tone or the little tune section of the same tune, the short break of the different tune. To solve this contradiction, it is necessary to develop a method that is simple, easy to operate, and suitable for various performances. It is the best choice to configure an additional structu...

Problems solved by technology

However, this method is only suitable for programs with large tunes in the same tone and long breaks in different tunes due to the need for a period of time for changing, and cannot continuously change the pitch or small tunes in the same tune and short breaks in different tunes.
