扬琴是民族乐器中的“直嗓子”乐器,许多扬琴演奏家为使扬琴奏出“曲线”音型曾做过不少的尝试。由于现代扬琴的琴身增大,弦的张力也随之增大,不但给扬琴演奏“揉弦”带来很大困难,而且也容易跑弦。至于“滑音指套”新技法,所滑出的颤音很虚,不能与原音色统一,听起来很不协调。 Dulcimer is a “straight throat” instrument in ethnic musical instruments. Many dulcimer players have done a lot of attempts to make the “curve” type dulcimer. As the body of the modern dulcimer increases, the tension of the strings also increases. This not only brings great difficulty to the dulcimer dithering, but also makes it easy to run. As for the “slippery tone finger” new technique, the swaying vibrato is very empty, can not be unified with the original sound, sounds very uncoordinated.
