新中国成立以来,音乐工作者对笙进行了重大的改革,各种不同类型的改良笙相继问世,大大增加了笙的艺术表现力。改革的方法多为增加笙的扩展音域,设置共鸣管增大音量,增设笙键提高气息利用率。然而笙的重量也随之增加,如24簧至36簧的加键扩音笙,重量达1.5kg～4kg。如果选用较轻的材料制作以减轻笙的重量,就保证不了音色和音量方面的要求。重量的增加无疑给捧奏带来困难,它使胳膊、手腕、手指增加负荷而影响演奏;重量较大的笙因无法捧奏则只能放在腿上演奏。
Since the founding of New China, musicians conducted a major reform of the Sheng, various types of improved Sheng come forth one after another, greatly increasing Sheng artistic expression. The reform methods are mostly to increase the expansion of the Sheng Sheng range, set the resonance tube to increase the volume, increase the Sheng key to improve the utilization of breath. However, the weight of the Sheng also will increase, such as the spring from 24 to 36 spring PA sound reinforcement, weighing 1.5kg ~ 4kg. If you choose a lighter material to reduce the Sheng Sheng weight, it can not guarantee the sound and volume requirements. Increasing weight undoubtedly brings difficulties, it makes the arm, wrists, fingers increased load and affect the performance; heavier weight Sheng can not play because they can only play on the legs.
