Hulusi, as a unique Chinese national wind instrument, is loved by people for its rich and varied timbre and charm. However, in the course of performance, the problem of tubules intonation sometimes affects the overall musical effect. Mastering how to adjust tubules intonation accurately is one of the key steps to improve the performance level.

First, understand the importance of the tube and its intonation

Fenugreek usually contains a head and at least one appendage, which vibrates through the air stream to produce additional sound effects that add character and emotional color to the music. The accuracy of the appendage intonation directly affects the overall harmony of the whole instrument and the precise expression of the artistic conception of the music, so it is very important to ensure that the pitch of the appendage and the master is in harmony.

Second, analysis of the reasons for the incorrect pipe sound

1. Production process: Unreasonable design of the internal structure of the tube or production error may lead to intonation deviation.

2. Material changes: material expands and contracts due to temperature and humidity changes, which may affect intonation stability.

3. Player factors: uneven playing intensity or improper mouthpiece position may also lead to deviation from the standard intonation of the tube.

4. Improper maintenance: It is not cleaned or adjusted in time after long-term use, which may accumulate dirt inside the tube and affect pronunciation.

Third, the specific method of intonation adjustment

1. Physical adjustment:

Adjusting the length of the attachment: the end of the attachment has an adjustable part, which can be fine-tuned by changing the depth at which this part is inserted into the main pipe. In general, pushing inward will lower the pitch and pulling outward will raise the pitch.

Wall aperture correction: If the intonation problem is caused by the aperture error at the time of manufacturing, a professional can be fine-polished or reamed to achieve the required intonation.

2. Adjustment of playing technique:

Blowing force control: By properly adjusting the blowing force and Angle, sometimes you can also improve the intonation performance of the tube to a certain extent.

Breathing and breath use: Practice finely controlling the intensity and duration of breath to find the best way to produce accurate pitch.

3. Seek professional help:

For more complex intonation problems, it is recommended to consult a professional instrument repairman or maker, who can fix the intonation problem through more accurate measurement and debugging.

Fourth. Daily maintenance and maintenance

Check and clean the inside of the fenugreek regularly to avoid dust and moisture affecting the sound quality; At the same time, properly store the instrument and try to keep it in a constant temperature and humidity environment to reduce the impact of natural conditions on intonation.

In short, to solve the problem of inaccurate sound of fenugreek tube, it is necessary to take corresponding adjustment measures according to the actual situation, and through careful observation and practical exploration, in order to make each attached tube produce the most beautiful sound, so that the fenugreek performance is more perfect.
