How to sing well is as follows:

1. Open your throat. Opening the throat is very simple. When you are sleepy, yawn while talking, and the throat will open. Opening your throat is more important than opening your mouth. The voice you sing this way is brighter than if you just open your mouth without opening your throat.

2. The problem of changing the voice. The sounds in the middle and low ranges should be as wide as the high range, making it easy to transition. If the lower part is made too wide and stretched too much, it will be difficult to pass the transitional sound. When starting to sing upwards in the low and middle ranges, you must first think about the position of the high sound, and sing according to this sound position, and you will be able to pass smoothly.

3. Let the sound out. There are two things you must always do: first, put down your Adam's apple. Second, the diaphragm muscle is strong and supports the stability of the sound. The mouth forms a horizontal oval, not a vertical oval. If the outer mouth opens too wide, the inner mouth will become smaller.
