Cicada tirelessly uses a light and comfortable tone at any time, and can sing one light cicada song after another for people without any musical instrument accompaniment, which adds a deep affection to nature, and is called "insect musician" and "singer of nature". The high note in the cicada family is a cicada called "double drummer". There are large ring-shaped vocal organs on both sides of its body, and a disk that can be opened and closed inside and outside is in the middle of its body. The opening and closing speed of the disc is very fast, which is the reason for shaking cicada. The sound lacks change, but it is much louder than the canary in the jungle.
