Bawu is a kind of wind instrument which is very distinctive among Chinese traditional national musical instruments. The following are mainly aimed at the common difficulties encountered in the training of basic skills for beginners, and put forward some ideas, hoping to give some guidance to learners, so that when they encounter similar problems, they can Do some reference.

1. half hole playing technique

The half-hole is a relatively difficult technique, and it can play some sounds that are not found in the normal full-pressing finger hole; moreover, if used well, the pitch is more accurate than the interdigital technique; at the same time, the half-hole is a prerequisite technique that must be mastered in the portamento technique. The relationship between the first finger hole and the treble is that the major second finger hole should master this playing method.

There are two specific ways to play: the first one is that our hands are generally round like holding an egg. When pressing the half hole, we can straighten the desired fingers alone, so that we naturally hold down the fingers. The inner half hole of the hole is opened, and the outer half hole is released, and the height of the sound is adjusted by hearing. If the sound is too high, lower it a little, and if the sound is too low, raise it a little. This method is suitable for use when the distance between the finger holes is narrow. , when it is difficult to move your fingers left and right; the second method is to move your fingers parallel to the treble direction, and adjust the left and right distance of the sliding with your hearing. Portamento technique is used when pressing a half hole. Both methods should be mastered and practiced separately.

2. portamento

Portamento is an essential part of Bau playing, a very charming playing technique. The movement training of a single finger or a single group of fingers (multiple fingers moving at the same time) requires patience and careful training. The method of movement is single or at the same time. Move left and right. The portamento moves toward the treble, the portamento moves toward the bass, and the compound portamento starts moving in the desired direction, and then returns to the starting point.

Many people use this sliding technique to simply move left and right. In fact, accurate training is not a parallel left and right movement, but a single finger or multiple fingers moving in a circle at the same time. The upward slide moves clockwise and the slide counterclockwise. Draw a small circle over the finger hole. It is especially important to note that glissando is more difficult to master, and it takes more practice to be as natural and smooth as glissando.
