How to learn the piano well
To learn piano impromptu accompaniment well, we should also practice the keys while learning music theory. A piece of music should be practiced with a variety of accompaniment schemes, which can achieve the effect of different chords and accompaniment sounds.
Practice various mode scales and chord connections every day (change the rhythm), practice on different keys, play a song well every week, and practice at least three keys. You can also ask a teacher who knows music theory and can create music to teach, so you can avoid detours and save time.
Learn the piano carefully under the guidance of the teacher. Teachers must listen carefully when explaining the knowledge of music theory, so that they can use it flexibly when learning the piano. After every piano lesson, you should go home and practice. If you don't keep practicing, you will feel stiff and the knowledge you have learned will be easily forgotten.
