Treatment method:

1. Strings collide with each other: Because the peg hole is too close to the line, the two strings are close to each other, and they will rub together and make a hissing sound when they vibrate. Treatment: Use a screwdriver to split the two strings that are rubbing against each other. For strings that are difficult to split, use a screwdriver to split them from above the saddle, and use a tripod between the strings to separate the strings.

2. There are debris between the strings: There are debris between the strings or between the strings and the bridge. When the strings vibrate, they will hit these debris and make a "hissing" sound. Hissing sound, processing: clean up these debris.

3. The strings rub against the string bar: If the string bar is not pressed tightly, the strings will rub against each other and produce noise. Use a screwdriver to press the string above the saddle, and you can judge if the noise disappears. . Treatment: Tighten the string bar screws.

4. The strings rub against the string-bar screws: If the strings are too close to the string-bar screws, they will rub against each other and produce noise when they vibrate. Treatment: Place cloth between the strings and the string bar screws.

5. The strings rub against the string pegs: If the string pegs are loose or in the wrong position and cannot effectively hold the strings, noise will occur. Use a screwdriver to hold the string pegs against the string pegs and you can tell if the noise disappears. . Treatment: Tighten the string pins or correct the position.

Scale practice:

1. Most scales can be used by all 8 fingers of the left and right hands. Practicing scales can train the balance ability of the fingers.

2. Scale practice can help you become familiar with the fingerboard phonemes. All scales are composed of 24 major and minor modes, and the European music we are most exposed to almost all belongs to these modes. Once you are familiar with the scales, you will be familiar with them in general. these modalities.

3. In fact, music is composed of complete or incomplete scales, especially the melody part.

⒋. The scale seems simple, but in fact it is very difficult to do well if it strictly requires uniformity, speed, and granularity.

⒌. Add different rhythms, accents, and dynamics to your scale exercises, and use all imaginable right finger combinations.

Require students to practice using any imaginable combinations of im, ia, ma, pi, pm, pa, ich, mch, ach, ami, ima, mia, mai, pima, pami, etc. , some combinations may lack practicality, such as the combination where the ch finger is added, but it is very useful for training the right finger) You will find that scale practice is really broad.

⒍. Scale exercises play a great role in training the coordination ability of left and right hands
