I am a children’s music teacher. Have experienced the color empty drum of normal state of mind.

I can give you these points for reference.

1. Because it relies on the vaginal cavity to make sounds. The volume of the singing cavity is large, and the sound effect of the singing is good. So if I were to suggest, choose their 12-inch large drum.

2. There are three sizes of hollow drums with the same material. The large one is 12 inches. The key of the medium 10-inch drum is C. Suitable for general entry. Many simple scores are also in the key of C. The medium size is suitable for playing by yourself, or if you don’t have much space at home. The large size is perfect for sharing, or for parents and children to get together.

3. The size of the trumpet drum is 8 inches and is in the key of F. It goes well with Guqin. As an accompaniment or lead instrument. Not recommended for beginners.

4. The normal color of the heart is an empty drum with a full-tone drum. Because there are two tones, 47. There are more scores to play. Personally think. Because its vocal cavity is relatively flat. The voice is softer. Full sound suitable for entertainment and performances. But the charm of traditional culture is also weaker.

5. Finally, let me talk about my personal feelings. Se Kong's voice is so comfortable. When I play by myself. There is a lingering feeling.
