Excuse me, how to divide the piano? What does each key mean?

Black keys on the piano keyboard, used to play different levels. Function is to raise or lower the basic sound level.

Higher, shorter and narrower. There are 36 black keys keys in the 188 keys of the piano keyboard, and 5 black keys degrees in each group of 12 keys. Black keys's play is basically the same as the white key.

In the staff, the level change does not necessarily represent black keys, but black keys can only be represented by the level change. In the white spectrum, the changing sound level must represent black keys, while black keys can only be represented by changing sound level.

The sound group in the center of the piano series (that is, the seven sound groups from the center C in keyboard instruments such as piano and electronic organ) is called the minor group, and the sound groups that are one time, two times and three times higher than the minor group are called the minor group II, the minor group III and the minor group IV respectively, and the sound groups that are lower than the minor group 1 are named as follows.

Extended data:

1, scale

The 24 tonic tones of the scale are more important and useful. Many large sonatas, music and concertos have scales in many places, so we should master the scales well.

2, arpeggio

The arpeggios include 24 major and minor arpeggios, followed by 7 arpeggios. This is something based on scales, which is mainly used to practice the stretching ability between fingers, and it is also a very important exercise.

3, octave

There are two kinds of 8-degree play, 1 only wrist technique, and the second is to do it with arms and wrists. If you play an 8-degree segment, you need wrist skills.
