Did you know that singing out the air is actually a technical job?This technique will make your voice softer and more natural, and it will also enhance the richness and expression of your tone. Next, let's talk about the secrets and practice methods of qi sound pronunciation in simple terms. 
First, let's talk about a few key points in the pronunciation of air sound. 1.To master the rhythm of breathing, if you want to sing the breath sound, you must first learn to use the abdomen to inhale and exhale, and master the depth and regularity of breathing by adjusting the contraction and expansion of the abdomen. At the same time, learn to control the speed of your breathing, so that your breath comes out like a trickle, neither in a hurry nor slowly. 2.Keep your throat relaxedRemember, the most important thing in singing out the air is to keep your throat relaxed. When singing, it is best to place your larynx as naturally as possible, without overexerting force or strain, so that the voice can flow more freely. 3.Relax the vocal cords in order to sing a good voice Secondly, we must practice Xi to relax the vocal cords, because only in this way will the singing voice be gentler and more natural. When singing, the vocal cords should maintain a certain degree of relaxation, and never be too tight or too hard. 4.Oral controlIn addition, we need to master the control of the oral cavity. When singing, the mouth needs to be opened to the right level so that the voice can be heard clearly and naturally. The resonance effect in the mouth is also very important, so that the sound can be layered and infectious. 
So, how do you train?1.Breathing training starts with lung capacity. You can Xi breathing control by jogging, brisk walking, or deep breathing. 2.Throat Relaxation TrainingThroat Relaxation Training keeps the larynx in a natural, relaxed state. You can try methods such as opening your mouth and twisting your head, which is simple but very effective. 3.Vocal cord relaxation training allows the vocal cords to be fully relaxed by making "hissing" sounds, coughing, etc. 4.Oral Conscious TrainingConsciously train the oral cavity so that you can grasp the opening size and resonance effect of the oral cavity when singing. Reading poetry, singing and other activities are good training methods, which can not only improve oral control ability, but also broaden the aesthetic surface. 
All in all, in order to sing pneumatic singing techniques, it is necessary to understand and master the correct breathing techniques, laryngeal relaxation techniques, vocal cord relaxation techniques, and oral control. In addition to theoretical knowledge, it is necessary to practice Xi and constantly pursue progress. I hope the above explanations and introductions can help you better understand the skills of qi and voice, so that everyone can show extraordinary expressiveness at the moment of singing!
