弹奏中有时钢琴弦会被弹断;甚至静置时也有断弦情况发生,不过这种情况极少。断了的弦不要随手将它丢掉,尤其是低音区的缠弦。弦断了必须配上与原来规格一样的弦,其中包括弦的直径、缠弦铜丝的型号以及弦的长短等。如果不是这样,就会产生下列一些毛病:同音组中两根弦如果直径一大一小,小槌击弦时粗的承受的击力就大,细的承受击力就小,由于受力不均等,发音就不会完全一样;另外直径不同又关系着两根弦的张力,在相同频率前提下,粗的拉力 Sometimes the piano strings are played off during play; there is a broken string condition even when standing, but this is rare. Broken string do not readily throw it away, especially in the bass area wrapped strings. Strings must be accompanied by the same specifications as the original string, including the diameter of string, wrapped string copper wire models and the length of the string. If not, there will be some of the following problems: homophone two strings if the diameter of a big one small, small hammer striking the rough when the hit force is large, thin bearing force is small, due to unequal force , The pronunciation will not be exactly the same; also different diameter and the tension of two strings, under the same frequency premise, the rough pull
