声乐演唱作为一种技能、艺术实践必须要有丰富的实践来指导。就声乐学习而言,没有理论指导的实践是盲目的、危险的。我们在发声练习及训练上只有用理性的理论来指导才能获得发声状态的准确性、稳定性和相对的科学性。两者相辅相成、缺一不可。 Vocal singing as a skill, artistic practice must have a wealth of practice to guide. As far as vocal learning is concerned, the practice without theoretical guidance is blind and dangerous. We can only get the accuracy, stability and relative scientificalness of vocal states by using rational theories in vocal exercises and training. The two complement each other, are indispensable.
