I have no confidence in myself, because others say that I can't sing well and I dare not sing in the music exam. What should I do? How can I build my confidence?

Hello: First of all, you need to know whether your voice is suitable for singing. You can try to sing a paragraph and record a paragraph. Although there will be some sound changes, it can still express melody, intonation and sound quality. It doesn't matter if you don't have confidence. Some people are shy when they have a good voice. Besides, in front of so many people. Moreover, even if the voice is not good, as long as the rhythm and intonation are well grasped, generally speaking, music teachers will give high marks. Everyone has his own special voice. You can try to play your voice to the extreme from one angle.
