This is a commonly used technique in guqin performance, the purpose is to make two, or three, four sounds can be closely connected.

The so-called "one" refers to either the big finger or the name finger. No matter what finger, when pressing a finger, you must hold down one, two or three strings at the same time.

Only the finger force of the string must be moved according to the movement of the right finger. For example, when the right finger plays the seventh string, the force point of the left finger is pressed on the seventh string. When the right finger plays the sixth string, the force point of the left finger moves to the sixth string at the same time...and so on.

When "pickling over two strings" (or over three strings), you must press the string with the inner joint (the part near the seam of the first joint of the ring finger pressing the string).

Due to the different thickness of the inner joint meat, you can choose the part where the meat is thinner and the bones are more protruding to press the strings to make the sound as bright and clear as possible. Then, move the force point in the finger from the treble string to the bass string with the movement of the string played by the right finger (not the movement of the force point), so that the sound and the sound can be closely connected.

All music pays attention to the handling of the relationship between sound and sound. The person who can really handle the relationship between all two sounds is a musician.

In the guqin performance, the sound is often broken because the sound is on two or several strings. In fact, it requires close coherence between the sound and the sound, and the key technique is "leave enough time and pass the string (shift) quickly".

"Leave enough time value" means that each note must be left with the time value indicated on the score. However, it must be "fast" when overstringing or shifting. The latter is also for the former, and the most important thing is the close connection between the sound and the sound.

"Overstring" refers to two or three notes on the "vertical" adjacent strings. "Shift" refers to the connection of two tones on laterally adjacent strings.

For example, the previous note is on the seven strings and seven emblems, and the next note is on the six strings, seven emblems and six. Then the previous note must stay for the specified time value, and then quickly move to the next note. Also, if the next note is to be moved to the six strings and nine emblems, then the previous note will be moved to the next note quickly after the predetermined time has been left.

The fingers should translate when moving, and no arc parabola should appear. As far as possible, leave no room for audible breaks during the movement.
