First, know whether to blow holes or suck holes.

Observe the metal sheet in the harmonica hole. In some holes, you can see the rivet (the reed head faces inward), but in some holes, you can see the reed without rivet (the reed head faces outward). Remember: "those who can see rivets should suck, and those who can see reed holes should blow." After seeing it clearly, try to blow or suck a hole with your mouth, one by one, and master the sound of each hole.

Second, learn the holes corresponding to each sound.

After knowing the holes for blowing or sucking, be sure to know the corresponding holes for each sound. Practice blowing or sucking, be familiar with the sound of each hole, and after repeated practice, you can blow or suck when you see the sound.

Be familiar with the holes corresponding to each sound.

You can try to play music after you are familiar with the holes corresponding to each sound. If you can read music, you can learn to play directly. It doesn't matter if you can't read music, but it's slower than learning harmonica. I suggest you find a simple song that you can sing first. Because the song can be sung, try to sing the soundtrack, and then learn to play. It shouldn't be difficult to learn. Remember: no matter what you learn, you must work hard. As long as you can persist, you will learn well. "You are not afraid of incompetence, but you are afraid of perseverance."

for instance

As we all know, "Happy New Year", if you can't read the music, learn to sing it several times with the music, and then learn to play. Learning musical instruments plays a very important role in improving intonation and reading music. Correct playing posture is conducive to the play of breath. You can sit or stand and play, just hold your head up, keep your eyes straight ahead.
