A brief introduction to the adjustment techniques of music materials used in music teaching activities is as follows:
1. Adjusting the instrument itself
1. Adjusting the bridge

Most musical instruments require adjusting the bridge to change the pitch, such as piano, guitar, guzheng, etc. Generally speaking, moving the bridge forward will lower the pitch, and moving the bridge backward will raise the pitch. The specific adjustment methods vary according to different musical instruments and brands. Generally, you can check the instrument manual or consult a professional maintenance personnel for adjustment methods.
2. Adjust the tension of the strings
Some stringed instruments need to adjust the tension of the strings to change the pitch, such as violin, eryihuban, laijishuoda, etc. . Relaxing the string will lower the pitch, and tightening the string will raise the pitch. This adjustment method needs to be adjusted according to the actual situation of the instrument to avoid damage to the instrument.
2. Use a capo
For string instruments such as guitars, you can use a capo to change the tone of the music. A clip on the fingerboard of the instrument can change the tension of the strings, thereby changing the pitch. When using a capo, you need to pay attention to the position and strength of the clip to avoid excessive pressure on the fingerboard.
3. Change the playing technique
In some special circumstances, the purpose of transposing can be achieved by changing the playing technique. For example, when playing a wind instrument, the pitch can be changed by changing the shape of the lips and air pressure; when playing the piano, the timbre and pitch can be changed by changing the strength and speed of the fingers; when playing a string instrument, the timbre and pitch can be changed by changing the strength and speed of the fingers; position on the string to change the pitch.
In short, instrument transposition is a very practical technique. It can be adjusted according to the needs of the performance and the actual situation of the instrument playing.
The music is more colorful and expressive. However, you need to be careful when transposing, and do not make excessive adjustments, so as not to affect the overall effect of the music and the normal performance of the instrument. According to different musical instruments and performance needs, the methods and techniques of transposing are also different, and they need to be used flexibly according to the actual situation. In addition to the methods mentioned above, there are some other transposition techniques and methods that need to be explored and practiced according to specific circumstances.
