It's really helpful for self-study. The courses on the app are perfect, and there are various modes to help practice when playing. The music library is also very rich. You can choose your favorite music score at will, and flowkey will practice with you. I have studied for a while now and can play many songs.
Learn piano skills:
First of all, we should be mentally prepared. Learning piano is a long and boring process. Secondly, we should find a good teacher to study systematically. Accurate hand shape, fingering, exertion, reading ability and sitting posture are very important for piano performance. A good teacher can help find a quick way to get started.
Finally, get into the habit of reading music and solfeggio. In short, we should improve the piano skills through persistence and deepen our understanding of the works through repeated chewing.
