The following four points include strength, length, light and shade, and thickness. When you master it proficiently, you can basically find the timbre you want.

1. Relax

When playing, the power should be concentrated on the fingertips, the arm should hang down naturally, the arm and the wrist are a way of conduction, don't be nervous, let the power flow to the fingertips naturally, without loss, and pass through.

2. Force speed

When playing, the speed of touching the strings when the fingers and the strings are in instant contact should be slightly slowed down. The fingernails should be attached to the strings as much as possible to touch the strings. The sound should be long and not too grainy. For example, , touch the strings too fast, and the sound starts to jump up.

3. String position

The change of the string position also plays a big role in the timbre. When we play the middle and high notes, we can move slightly to the right to seek a bright timbre. You can use the position close to the middle to play, strengthen its reverberation, and give people a quaint feeling.

4. The depth of touch

The depth of the touch string is mainly reflected in the thickness of the timbre. If the fingernail is slightly deeper and the touch surface is large, the pronunciation will be thick and full. will be clearer.
