古钢琴是一种弦乐器。这意味着它的声音是由琴弦振动产生的，琴弦被称为“切线”，由一个键操作。弦越长，发出的声音就越低。弦的一端与谐振器（音板）紧密相连。另一端连接到仪表箱的相对边缘。切线位于弦下两端之间的某个地方。当你按下键时，切线撞击键并粘在键上，使其成为振荡节点（螺母）之一。只要握住键，切线就会粘在弦上。当你松开琴键时，琴弦的正切线就离开了，琴弦的振荡也就停止了。击弦古钢琴有两种基本类型。无调型：每个音都有自己的弦。微扰型：一个字符串有两个（或三个）相邻的键（限制复调）。通常，这些琴弦成对使用可以发出更强的声音。当切线在节点上撞击弦时，只产生轻微的振荡，它不能发出响亮的声音。
A clavichord is a chordophone instrument. This means that its sound is produced by vibration of the strings hit by metal blades called “tangents” which are operated by a key. The longer the string is, the lower tone it gives. One end of the string is hard attached to an resonator (soundboard). The other end is attached to the opposite edge of the instrument case. The tangent is located under the string somewhere in between its two ends. When you press the key, the tangent strikes the key and sticks to it making itself one of the oscilation nodes (nut). The tangent sticks to the string as long as the key is held. When you release the key, the tangent leaves the string and its oscilations therefore stop – the tone mutes. There are two basic types of a clavichord. Unfretted type: each tone has its own string. Fretted type: a single string is there for two (or three) neighbouring keys (limiting the polyphony). Usually, the strings are available in pairs to give stronger sound. As the tangent strikes the string in the node producing only light oscilations, it cannot give loud sound.
