在平时日常学习中大家经常发现很多人唱歌，下巴非常紧张，下巴是一块骨头，骨头不是肌肉怎么紧张呢？所谓下巴的紧张，其实是这么两条肌肉作怪：他们窠舌骨肌和二腹肌前腹，这两条肌肉牵动着歌唱的两大器官，舌头和喉结的紧张，必然造成下巴前伸和压喉造成高音难声音硬。声乐练习者往往存在着这样那样的发声问题，如，喉咙挤卡、鼻音、舌头僵硬等。这些问题的成因，很多并不是 “方法”造成的，多数是自身发声器官无法完成大脑所给出的信号所指示的动作姿态，就是“想得到，却做不到”肌肉无法做到这些动作，原因就是，缺乏锻炼，嗓音机能训练是声乐学习的基础。我通过学习训练，在导师的帮助下总结了一些行之有效的嗓音机能锻炼方法，对声乐学习起到保健和促进作用，对嗓音机能训练的研究是当今声乐发展中重要的一部分。

In ordinary day-to-day learning we often find many people singing and chin is very tense, is a jaw bone, the bone is not how muscle tension? The so-called chin tension, in fact, is so two muscle mischief: they hyoid and the abdominal muscle before the abdomen, the two muscle affect the singing of the two major organs, the tongue laryngeal tuberculosis and the tension will inevitably lead to pressure jets and chin Protrusion A difficult treble voice hard. Vocal practitioners often there are a variety of vocal problems, for example, throat crowded cards, nasal, tongue, and so rigid. The causes of these problems, many are not "method" created by the majority of their own vocal organ is the brain can not be completed by the signal is given instructions by the action posture, that is, "want, but can not" muscle can not do these movements, The reason is that, the lack of training, voice training function is the basis of vocal learning. I learn through training, summed up some effective method of voice training function, learning to play a vocal role in promoting health and the training of voice function is important in the development of the contemporary vocal part.
