《毛诗序》中说:“情动于中而行于言,言之不足故嗟叹之;嗟叹之不足故永歌之。”由此可见,歌唱来自人们在劳动生活中的情感表达的需要。由古至今,歌唱都是人类用以抒发情感和交流思想感情的最自然、最亲切、最直接的一种艺术形式。歌唱艺术是通过以声传情、以情感人来进行的艺术再创造过程。 “Maoshi Preface” said: “Emotion in the line and in the words, the lack of words so sigh; sigh enough to eternal song.” Thus, singing from the people in the emotional expression of working life Need. Since ancient times, singing is the most natural, friendly and direct art form that human beings use to express their feelings and to exchange thoughts and feelings. The art of singing is the process of recreating the art performed by emotional people through the use of voice.
