Accompanied by 6, 3 and 2 respectively. I didn't bring my piano. Let me feel it. Divide music into four sentences. Count it yourself. Start with six partners, the first sentence ends with 73 instead of three partners, continue ... The second sentence ends with 6 partners, the third sentence ends with 2 partners as 4-32, the third sentence ends with 3-6 (the bass can't be marked) and then changes back to 6 partners, the fourth sentence starts with 2 partners, then uses 6, and finally uses 6. It's done.

what can I say? If you are really anxious, QQ will add me a video to praise you. My QQ45594394. Accordion must be written for authentication, otherwise it will not be added.
