Singing breath is the most important in the whole vocal function series. It is necessary to make clear the importance of breathing and pay attention to practicing the basic skills of singing breath.

We should also make good use of the * * * sound of singing. To make the sound spread far, the singer should vibrate the sound at the * * * sound point in the head cavity above the nasopharyngeal cavity by means of vowel conversion, stabilizing the throat to open the mouth and adjusting the breath, which can increase the volume, expand the range, beautify the timbre and unify the sound area.

At the beginning of vocal practice, it is necessary to sing intervals, scales and vocal sentences beautifully.
