About the project: 1. The wah-wah tube, also called the wah-wah tube, is a small percussion instrument with a simple structure but a magical sound. 2. The wah-wah tube is made of metal, and the frosted surface ensures an excellent hand feeling and is not easy to leave fingerprints. One end of the wah sound tube is sealed, the other end is open and has a long slot, and there is a small hole on the side. Produces a long, clean tone by hitting the sides of the opening. 3. After tapping, the small hole on the side can be opened and closed with the thumb to produce a magical wah-wah sound, just like the cry of a baby, which can produce unique sound effects in music and form a special sound field in sound healing.
