If it is for hobbies, you can choose to teach yourself. It's just that self-study is really laborious, and it's hard to say that you can learn the piano well without strong self-control ability. Therefore, if you have a certain economic reserve, it is recommended to find a teacher to study.

If you want to practice piano more professionally, you must find a teacher, and you must find a teacher in the offline training center. You can't register online. That kind of basic knowledge is for you to listen to, but there will be many problems in your own practice, and the teacher can't guide you one by one.

Introduction to piano:

Piano (Italian: pianoforte) is a keyboard instrument in western classical music and has the reputation of "the king of musical instruments". It consists of 88 keys (52 white keys and 36 black keys) and a metal chord board. Italian Bartolomeo Christofi (1655- 173 1) invented the piano in 1709.

The range of 88-key piano ranges from A0(27.5Hz) to C8 (4 186.0 108 Hz), while the key 108 is as high as B8(7902. 13Hz), which covers almost all the tones in the music system except the organ. Piano is widely used in solo, ensemble and accompaniment performances.
