钢琴有琴弦二百余根,一架钢琴全部琴弦的张力总计为十八到二十吨。因此,现代钢琴的琴架是铸铁制件。早期的钢琴由于弦架用材和结构的不合理,琴很容易走音,往往在音乐会上的幕间还得临时调音。因此,那时的钢琴独奏音乐会,演奏者必须聘用一位钢琴调律师随场,以保证音乐会间钢琴音调的准确。于是,一些乐器改革者曾别出心裁地进行过一系列革新。1854年,有人竟提出一项这样的专利申请,即所谓的“革除弦架的发明”。没有了弦架,弦无所附,怎么办?他干脆把弦张在琴后的墙壁上结果是可想而知的。
Piano has more than two hundred strings, a piano all strings tension total 18 to 20 tons. Therefore, the piano frame of a modern piano is made of cast iron. Early piano Due to the material and structure of the string frame unreasonable, the piano is easy to walk, often have temporary tuning in the concert screen. Therefore, at that time, the piano solo concert, the performer had to hire a pianist to attend the pianist to ensure the accuracy of the piano tone during the concert. As a result, a number of instrument reformers have taken the liberation of a series of innovations. In 1854, some people actually proposed a patent application, the so-called invention of “stripping string.” Without the strings, the strings are unattached, what to do? He simply put the strings on the wall behind the piano, the result is predictable.
