General fingering:

1. The movement of the middle thumb and the crossing of other fingers are the key to the movement. When the arm moves outward, the thumb moves through the round hole formed by the third and fourth fingers. When crossing, the rotation of the wrist is used to realize the transmission of power. The outward movement of the arm and the slight tilt of the wrist to the outside give the thumb a certain space, so that the thumb touch key and the key separation of three or four fingers are coherent and integrated. ?

2. "Universal fingering" suitable for playing arpeggios in eleven tones, namely C, G, F major and a, b, c, d, be, e, f, g minor key. ?

3. The "universal fingering" suitable for playing arpeggios in five major keys, namely D, A, E, B and bG major.

4. The "universal fingering" suitable for playing arpeggios in six tones, namely bE, bA, bD major and #g, bc, #f minor.

5. The transfer of power is achieved by the beating of the palm, which will cause the performance to be disconnected and jump. The arm movements are translational, and there must be no up and down bumps. The rotation of the wrist adjusts the direction and movement space of the fingers, so that the fingers can be more comfortable and stretched.

Extended information:

1. The practice of arpeggios is a basic course for piano learning. It is very important for being able to play some piano works completely and accurately in the future and improving students' performance skills. An important purpose of practicing scales and arpeggios is to perform the tones that make up the scales and arpeggios evenly and coherently.

2. The practice of breaking up arpeggios can give each finger of each hand the proper exercise. Especially the exercises for the left hand should be given more attention. Those fingers with weaker finger strength also need care. Only in this way can the scales and arpeggios be played evenly.
