Description

  The present invention relates to a slide lever type chromatic harmonica that can produce two kinds of scales, a major scale and a semitone higher than this by moving the slide lever.

The chromatic harmonica has a slide lever between the main body and the mouthpiece. The main body has a large number of whistle chambers each having a lead as a sounding body, and a large number of blow holes for blowing and sucking air into each whistle chamber are provided in two rows in the vertical direction. One row of whistle chambers has a long scale sound arrangement, and the other row of whistle chambers has a semitone scale arrangement (this arrangement is called a “straight arrangement”). The slide lever is provided with two rows of upper and lower openings in which the openings for opening the blow holes in the whistle chamber and the closing portions for closing the holes are alternately arranged. Since the opening of the slide lever has a one-to-one correspondence with the blowhole of the whistle chamber, the number of both is the same. By moving this slide lever in the horizontal direction, it is possible to close either the major scale whistle chamber row or the semitone scale whistle chamber row and selectively produce the sound of either scale. (For example, Patent Document 1). Here, “up / down”, “left / right”, “front / rear” means the top / bottom / left / right and front / back as viewed from the performer in the performance state of the harmonica.
In addition, there is a chromatic harmonica in which two scales of whistle chambers are assigned alternately with a major scale sound and a semitone scale sound, and the sounds of each scale are arranged in a staggered pattern in the horizontal direction. Called.). The slide lever in this type of harmonica has one opening and a closed portion corresponding to two whistle chambers in common, so the number of openings is approximately half the number of whistle chambers.

JP 2004-219732 A

Among the above-described conventional chromatic harmonica, in the former, that is, in a straight arrangement, the opening of the slide lever is arranged between the blow holes of adjacent whistle chambers when not used as a vent. Therefore, the lateral width of the opening must be equal to or less than the interval between adjacent blow holes. For this reason, the size of the opening of the slide lever is limited to about half the size of the blowhole of the whistle chamber.
In the latter, that is, in the cross arrangement harmonica, the opening of the slide lever is always used, and there is no need to wait between adjacent blow holes. For this reason, the size of the opening of the slide lever can be expanded to the same extent as the size of the blowhole of the whistle chamber. If the opening of the slide lever becomes large, the amount of air blown into the whistle chamber increases, and a large volume can be obtained. However, since the moving stroke of the slide lever becomes longer, it takes time to switch the scales, resulting in inconvenience in performance.
Accordingly, an object of the present application is to provide a chromatic harmonica having a cross arrangement in which the moving stroke of the slide lever is relatively short, the scale can be switched in a relatively short time, and the smoothness of the performance is not hindered. It is said.
