钢琴是通过什么而发音的乐器 麻烦速速回复！

钢琴是通过琴弦的振动而发音的乐器。当演奏者按下钢琴键时，琴键会带动琴槌敲击相应的琴弦，使琴弦振动并产生声音。这些振动通过钢琴的共鸣板（即音板）和共鸣腔放大，最终形成我们听到的丰富而美妙的音乐。

In English, the piano is an instrument that produces sound through the vibration of strings. When the player presses a key on the piano, the key causes a hammer to strike the corresponding string, making it vibrate and produce sound. These vibrations are amplified by the piano's soundboard and resonant cavity, ultimately forming the rich and beautiful music we hear.
