Abstract

The utility model relates to a pipe instrument, namely a modified multi-hole bau, wherein a blow hole and a sound hole are opened on a tube-shaped body, the numbers of the sound hole are 10-13, the positions and the sizes of the sound holes are corresponded with hand shape positions on instrument which is held by double hands under the premise without breaking law research. Compared with the traditional seven-hole bau, the modified multi-hole bau has the advantages that the appearance and conformation of a traditional instrument are basically not changed under the premise without changing traditional playing techniques and styles, the modified multi-hole bau guarantees natural hand shapes, flexible fingers and convenient performance, which is further opened with a semit hole which is normally used, and twelve sounds are tended to be complete, which are convenient for playing modulation, semi gamut and complex intonation music.

Description

Improvement porous crust crow

Affiliated technical field:

The utility model relates to a kind of wind instrument, particularly the crust crow.

Background technology:

Crust crow now commonly used be a seven apertures in the human head, and the more works difficulty of performance modulation or variation sound is bigger, present situation for a change, and much people have proposed variously to add the key scheme, have enriched scale though add key, have changed the playing style of musical instrument; The range of having widened musical instrument that has, but the more works of the less difficult performance variation sound of semitone.

Summary of the invention:

The purpose of this utility model is to overcome above-mentioned not enough problem, and a kind of improvement porous crust crow is provided, and simple in structure, it is complete that twelve-tone is tending towards, and keeps traditional playing technique.

The technical scheme that the utility model is adopted for achieving the above object is: improvement porous crust crow, offer on the tubular body and blow hole and sound hole, sound hole quantity is 10-13, and the position of sound hole and size are under the prerequisite of the study of law, and the hand shaped position of holding musical instrument with both hands is corresponding.

The musical instrument tubular body is held on described right side, offers 10 sound holes on the tubular body, the corresponding sound hole of left hand little finger of toe, its particular location pronounce by left hand little finger of toe symbol by the right hand all open the minor second interval relation position, top that accords with of pronunciation; The nameless corresponding sound hole of left hand, particular location for open simultaneously the nameless and left hand little finger of toe of left hand pronounced to accord with by only open the whole sound holes of the right hand pronounced above major second interval relation position; The corresponding big sound hole of left hand middle finger, the corresponding big sound hole of left hand middle finger are positioned at a sound top major sixth (5/1 and concern the position; The corresponding big sound hole of left index finger, it is positioned at a pure octave in sound top and concerns the position; The corresponding big sound hole of left hand thumb, it is positioned at major second interval relation position, the corresponding sound hole of forefinger top; The corresponding sound hole of the every finger of the right hand is the semitone interval relation between right hand little finger of toe and the tube sound, and the distance between the corresponding adjacent sound hole of right finger is all the semitone interval relation.

Offer 11-13 sound hole on the described tubular body, wherein the corresponding sound hole of one or more fingers in left hand middle finger, left index finger, the left hand thumb is two little sound holes, corresponding two the little sound holes of left hand middle finger, be the semitone relation between two little sound holes, the top minor second that the corresponding inboard little sound hole of left hand middle finger is positioned at the nameless corresponding sound hole of left hand concerns the position, and the little sound hole in the left hand middle finger correspondence outside is positioned at a major sixth (5/1 interval relation position, sound top;

Corresponding two the little sound holes of left index finger, interval relation is a major second between two little sound holes, the corresponding inboard little sound hole of left index finger is positioned at minor second interval relation position, the corresponding sound hole of left hand middle finger top, and the little sound hole in the left index finger correspondence outside is positioned at a pure octave in sound top and concerns the position;

Corresponding two the little sound holes of left hand thumb, interval relation is a minor second between two little sound holes, the corresponding little sound hole of musical instrument tail end partially of left hand thumb is positioned at minor second interval relation position, the corresponding sound hole of left index finger top, and the inclined to one side musical instrument of left hand thumb blows the little sound hole of nose end and is positioned at major second interval relation position, the corresponding sound hole of forefinger top.

Described left side is held on the musical instrument tubular body sound hole position exchange right hand and is held sound hole position on the musical instrument tubular body.

The utility model is compared with traditional seven apertures in the human head crust crow has significant advantage: it does not change under the prerequisite of traditional playing technique and style in assurance, substantially do not change traditional instrument profile and structure, guarantee that hand shape is natural, finger is flexible, it is convenient to play, increase the most frequently used semi note hole, make twelve-tone be tending towards complete, be convenient to play modulation, chromatic scale and complicated mode melody.
