Portamento always feels wrong when playing Erhu? Today, I will tell you about the problems that are easy to occur in playing portamento. The main problems are as follows:

1. The sliding speed of the left hand is uneven, and there is a pause in the middle, so that the portamento is intermittent.

2. Portamento does not match the time value it should occupy.

3. The head or tail of the up-and-down glissando is played too full, and the part that should be hidden is not hidden; or the process of fading in and out is played unnaturally, making the portamento appear stupid and rigid.

4. Blind use of portamento, without choice and sublation, makes the music a sticky piece like dough. (When playing portamento, you must first understand the background and style of the music, and then choose a technique that matches the style and mood of the music)

5. The pitch of the pad finger slide is not good.

6. The pad finger glissando is not round, and the fingers have "sills" in the transition process, which makes the pad finger slide into a three-section portamento.

7. When playing back portamento, the sound head is not full, and even "eats" the sound head, which makes the back portamento into an up portamento, and does not play the role of back portamento to strengthen the sound head. (Especially pay attention to the process of playing)
