钢琴的弦列部分是指排列在铁支架上的所有弦。它的特点是弦振动的频率与各该键上的音名相符。一个键上的弦是由一根、两根或三根弦组成的,弦列部分由左至右分为低、中、高三个音区。在低音区内,为了得到较低频率的音,通常采用缠弦。在缠弦中,又有单层缠弦、双层缠弦两种,缠弦由软铜丝缠绕钢丝而制成。中、高音区内,基本上是由裸弦(即乐器用琴钢丝)组成。在中、低音交界处,为使中、低音音色过渡均匀,在中音区 C-D#之间有时采用缠弦,来达到统一音色的目的。钢琴的音量,它在弦列上取决于弦的质量和张力。弦的质量与弦的长度、直径有 Piano part of the string refers to the arrangement of the iron bracket on all the strings. It is characterized by the frequency of string vibrations consistent with the pitch of each key. A key string is composed of one, two or three strings, part of the string from left to right divided into low, medium and high three sound zone. In the bass area, in order to get a lower frequency tone, usually wrapped around the string. In the winding string, there are single-wrapped string, double-wrapped string two, wrapped string made of soft copper wire wound. In the high-pitched area, it is basically composed of a bare string (ie a musical instrument with a steel wire). In the middle and bass junctions, in order to make the middle and bass sound transition evenly, sometimes in the midrange area C-D # wrapped around the string, to achieve the purpose of unified tone. The volume of the piano, which depends on the quality and tension of the strings in the strings. The quality of the string and the length of the string, the diameter there
