筝是我国富有特色的一种民族乐器,已有两千多年的悠久历史。传统筝由于音量小,音域窄,按五声音阶排列,既不便演奏七声音阶的旋律,更无法在乐曲进行中转调,在音乐表现上有很大的局限性。近年来,我国一些乐器制造者和音乐工作者对传统筝进行一系列的改革,取得了很大成绩。但是仍然遗存一些问题,特别是转调问题,和转调后音准问题还没有得到理想的解决。因此,用于独奏时还不能适应现代乐曲的需要,参与乐队合奏也有一定困难。
Zheng is a national musical instrument with rich characteristics in our country. It has a long history of two thousand years. Due to its small volume and narrow sound range, the traditional kites are arranged in five-tone scales, which makes it difficult to play seven-scale melodies. Moreover, traditional kites can not be transferred in tune and have great limitations in musical performance. In recent years, some musical instrument makers and musicians in our country have carried out a series of reforms on the traditional kites and made great achievements. However, some problems still remain. In particular, the problem of transfer and the issue of pitch after transfer have not yet been satisfactorily solved. Therefore, when used in solo, it still can not meet the needs of modern music, and there are some difficulties in participating in band ensembles.
