Transposition, in order to express different musical content, the composer has indicated at the beginning of the score what key to play the piece in, for example: 1=C; 1=F, etc. When we play Hulusi and Bawu, we can choose to replace the musical instrument of the corresponding key to play according to the key signature requirements of the repertoire. This is a kind of modulation method. Another modulation method can be performed on the instrument. This modulation method requires moving the cucurbit flute and the Bauben tune "do more (1)". To change the key of F, make "re rui (2)" with a tuba. To switch to D key, use the drum tone for "fa" (4) and then change other fingerings accordingly.
Due to the limitation of sound range and scale arrangement, the commonly used traditional cucurbit flute and bawu can only play four tones each. 1. Open the third hole for "do (1)" and make the fingering table of "sol (bass 5)" (ie: this tone), including the bass "mi (bass 3). 2. Open the third hole for "fa" (4) The fingering table of "do (1)" for the barrel tone. Including the bass "la (bass 6)". 3. The third hole is opened to make "sol (5)" The fingering table of "re (2)" for the barrel sound .Including the bass "si (bass 7)". 4. The fingering table of the bass "fa (bass 4)" for the barrel tone. Including the bass "re (bass 2)".
Note: The above four fingerings are based on the first one, namely: open the third hole for "do (1)", and the barrel tone for the bass "sol (bass 5)", that is, cucurbit flute. Bawu's native tone fingering is the most commonly used. However, the other three fingering learning also have practical significance, such as for the performance of other prescribed tunes or the transposition in the tune.
There are 7 sound holes on the head of the cucurbit flute. In theory, multiple tones can be played. However, due to the particularity of the phonemic arrangement of the cucurbit flute, there will be many restrictions when transposing. , semitone) changes, the fingering should be changed accordingly, some changes need to be realized by combined fingering or half-hole, etc., it is very awkward to operate, and has little practical value, so it is rarely used, such as the drum tone for 6 ., Tone for 7. and Tone for 3. etc.
The commonly used fingering of cucurbit flute is 5., 1.
"Fengwei Bamboo under the Moonlight" has a C-key version. The first half of the piece is played with small C-key cucurbit flute with a barrel tone for 5. The second half is played with big F cucurbit silk with a barrel tone for 1. The whole piece is played before and after. It is the key of C, there is no pitch change, but the fingering is changed when using the big F cucurbit. It is recommended that beginners focus on learning the 5. and the 1.
The relationship between the fingering of cucurbit silk and tonality is shown in the following table:
