How is the tone of cucurbit silk determined? Today, I will share with you the questions related to the tuning of cucurbit silk.
The temperament of an octave divided into twelve equal parts - a semitone is called the twelve equal temperament. If the pitch distance between two tones is equal to two semitones, it is called a whole tone, and if it is equal to one semitone, it is called a semitone. An octave (eg, from bass 5 to midrange 5, midrange 1 to treble 1, etc.) includes twelve semitones, or six whole tones.
A, B, C, D, E, F, and G are the names of the pitches; B-C and E-F between the two notes are each a semitone, which is unchanged. 1, 2, 3, 4, 5, 6, and 7 are roll-calls of the notes; 3-4 and 7-1 (bass 7-middle 1 or middle 7-treble 1) are also a semitone each, This is set when the cucurbit silk is made and the tone is set.
The cucurbit flute is a musical instrument that adjusts the tune, and the pitch of the third hole is the palace tone (1, do), which is the original tune of the cucurbit flute. The pitch is unchanged (except for fine-tuning) after the modulation is done, including five whole tones and two semitones. Therefore, it is necessary to consider the limitations of the range and scale (chromatic) when playing, and prepare several cucurbits of different tunes. (Most of the flute, Xiao and suona in the national musical instruments are like this).
Hulusi in the key of C:
5 whole tone 6 whole tone 7 semi tone 1 whole tone 2 whole tone 3 semi tone 4 whole tone 5 whole tone 6
G Whole tone A Whole tone B Semitone C Whole tone D Whole tone E Semitone F Whole tone G Whole tone A
Hulusi in B-flat:
5 whole tone 6 whole tone 7 semi tone 1 whole tone 2 whole tone 3 semi tone 4 whole tone 5 whole tone
F whole tone G whole tone A semi tone b B whole tone C whole tone D semi tone b E whole tone F whole tone G
Since the B tone is lowered by half a tone, it becomes B-b (A-b), and the original one semitone between BC becomes two semitones, (a whole tone), and the original whole tone between A and B becomes A semitone, maintaining the bass 7-midrange 1 is still a semitone, and between 1-2 is still a whole tone. The same is true for D-bE and 3-4.
Hulusi in G key:
5 whole tone 6 whole tone 7 semi tone 1 whole tone 2 whole tone 3 semi tone 4 whole tone 5 whole tone 6
D whole tone E whole tone #F semi tone G whole tone A whole tone B semi tone C whole tone D whole tone E
There are three semitones between E-G. Since the F sharp semitone E-#F is changed from semitone to two semitones (whole tone) and #F-G becomes a semitone. The latter question is not difficult to understand.
