1. First, practice 1, 2, 3 and 5 of the first and second holes. These four tones are ascending scales, while the other five, three, two and 1 are descending scales. With these four tones, you can play the first and second phrases of the music "Chinese cabbage". (The blowing sound of the first hole is 1, the sound absorption is 2, the blowing sound of the second hole is 3, and the sound absorption is 5. )

It doesn't matter if the novice blows at first, but if he practices more, he will be sure.

2. Continue to learn notes 5 and 7 of the third hole. The blowing sound of the third hole is 5, which is the same as the sound absorption of the second hole. However, when learning to play scales in the primary stage, only the third hole is played. Because in practical application, the blowing sound 5 of the third hole is much greater than the sound absorption 5 of the second hole. After learning these two notes in the third hole, connect them with the previous notes and play the ascending scale of bass: 1, 2, 3, 5, 7.
