I am 24 years old now. Have time to teach yourself the piano. Practice for about 4 hours every day. I don't want to take the exam if I want to pop up pop songs.

Uh, hello, beauty. You mean Canon, right? There are many versions of this song, the simplest of which can be regarded as one with only a few notes, but Pachbel is very difficult. Four hours is actually ok, not short, but I insist. Let's start with the score. I think since you're not going to play that kind of classical music, you can actually abandon the staff and use the simplified notation. Anyway, you're not going to take the exam. Also, be familiar with the keys, because the piano is a little different from other musical instruments. The most direct thing is that it is a chord, not a melody. So if there is no music theory, it will be very painful. You can learn a little by watching videos. It doesn't need much. Let me give you a suggestion. Although I can't play the piano, you can match the simplest melody with a chord and connect it. At first, you can shorten it. The main thing is that after you switch chords, you feel that the melody is ok, and then play a longer tune. Also, for music, the most important thing is to understand and appreciate. Don't be too rigid. For example, you can write a demo yourself, match a few chords and then play it out, so that you can understand sounds and chords quickly at the meeting. It's boring to practice alone, so create more fun for yourself. Mainly because the piano is a little dependent on music theory, this can't be helped. And practice as much as possible. This is the only way. I can't play anything with my unfamiliar hands. For Canon, it is my favorite in my life, hehe, so-called answer this question. However, it is actually just a technology, and there is no fixed score. You can play a single note by pressing a fixed pick, and you will know if you play more Canon, but the fixed version is more difficult. So don't play according to the difficulty at first, find some basic scores to try. Give you a few chords and you'll know. C, g, a, e, f, c, f, g come on, ............
