据绿润百科网站「郎朗花兒╮」消息，近日，标准钢琴有多少个琴键，请问钢琴总共有多少个琴键？引发热议，标准钢琴有多少个琴键同样引起许多争议，对此众网友各抒己见。但到底是怎么回事呢？绿润百科为您解答。

钢琴总共有88个键，其中有52个白键，36个黑键。钢琴是西洋古典音乐中的一种键盘乐器，有乐器之王的美称，普遍用于独奏、重奏、伴奏等演出。钢琴主要分为早期钢琴、现代钢琴和自动钢琴，现代钢琴从外形上主要分成立式钢琴和三角钢琴。

立式钢琴：

也称直立式钢琴，通常琴体上沿至地面的高度为1.1~1.3m，主要用于教学、家庭娱乐和弹奏练习。立式钢琴的弦是垂直方向的，所以击弦的方式是垂直敲击。在踏板的装置上，左踏板被称为弱音踏板，是为了帮助演奏者弹奏更弱的音或者变换声音柔和度；左踏板踩下后，琴槌更靠近琴弦，通过缩短敌击距离来减弱音量；中间的踏板被称为消音踏板，是为了不影响别人休息而设计的，其原理是立式钢琴里面装有一个带木条的毛毡，当踩下踏板时，毛毡就挡住了琴弦，从而让琴槌不能直接打在钢琴上，以减弱声音；右踏板又称延音踏板。
