If you encounter the problem of voicelessness in the high voice area during the performance of hulusi, you can investigate and solve it according to the following steps:

1. Reed deformation or material problems:

High voice silence may be due to the deformation of the reed after a long time of use or the aging of the material to lose elasticity. Check whether the reed Angle of the fenugreek is too small, if so, you can try to use non-destructive adjustment methods, such as by holding down all the sound holes, using the appropriate force to inhale a breath, so that the reed slightly raised, and then blowing with the same force to adjust to the appropriate position, to avoid too drastic action to cause damage to the reed.

2. Playing skills:

For instruments like fenugreek that require overblowing (playing octaves), players need to master proper breathing techniques and lip muscle control. To ensure that the breath is even and fast, coupled with the correct fingering, especially when playing the high notes, requires stronger breath support and more precise airflow control.

3. Maintenance and maintenance:

Check the overall condition of the fenugreek, including whether there is blockage, moisture accumulation and other problems. The fenugreek wire is greatly affected by temperature and humidity, so it should be stored and played in a suitable environment, and cleaned and maintained regularly to avoid affecting the working state of the reed.

4. Replace the reed:

If the above adjustments do not work, and it is determined that the reed itself is damaged or has insufficient elasticity, it may be necessary to have a new reed replaced by a professional to restore normal pronunciation.

5. Professional maintenance:

If you still cannot solve the problem after trying to adjust yourself, it is recommended to send the hulusi to a professional instrument maintenance point, so that the technician can carry out detailed inspection and maintenance to avoid further damage caused by the adjustment process.

To sum up, there are corresponding solutions for hulushi high tone silence, from adjustment of playing skills, simple maintenance to seeking professional help. Problems caused by different reasons need to correspond to different solutions, therefore, careful inspection and gradual investigation is very necessary.
