钢琴和弦查找器怎么用
这一页的每个和弦都能弹、能在键盘上看到、也能用构成音公式解释。下面说明卡片每一部分怎么读，以及读完做什么。
按名字或按形状找和弦
搜索框会边输入边筛整个曲库，C、Cm、C7、Cmaj7 各自直达对应和弦。下面两个筛选器按根音和类型收窄：十二个根音，配大、小、七、大七、挂留、减、增。根音加类型，是找到拼不出来的那个和弦最快的路。
键盘显示的是原位排列
高亮的键就是和弦的原位构成音，从低到高排列。最左边的高亮键是根音，键盘旁写出的音名也按这个顺序。先弹一次把形状听进耳朵，然后移开视线用手找到同样的键——示意的用处就在这里。
公式说明为什么是这些音
大和弦是 1-3-5，小和弦是 1-b3-5，七和弦加上七度，挂留替换三度，减和弦降低五度，增和弦升高五度。音程一行列出每个音到根音的距离，这就是你在任何调上都能搭出这个和弦、而不用背九十六个形状的原因。
转位让手不必移动
原位从根音开始；第一转位把根音升高八度，第二转位再升三度。三种排列音相同，所以选择和前一个和弦最近的转位，进行才会顺滑而不跳跃。按钮会逐个播放，方便听出差别。
指法两只手都写好了
RH 1-3-5 是右手拇指、中指、小指；LH 5-3-1 是同一形状镜像到左手。七和弦会伸到四个音，挂留和减和弦的数字会变。用练习链接在完整键盘上打开这个和弦，空格键就是延音踏板。
按和弦类别练习
先把十二个大和弦连着弹，再十二个小和弦，然后七和弦。把同一类连着听，比按歌曲需要的顺序学更快，因为手一次只需记住一种形状。
和弦是形状加理由。先在键盘上学形状，再用公式核对：两者对上之后，不看这一页也能在任何调里找到这个和弦。
常见问题
Search for the chord by name, or use the category filters to browse major, minor, 7th, maj7, sus, diminished and augmented families. Selecting a chord opens its detail view with the notes it contains and, on guitar, the fingering diagram for the shape.
Every chord has a play control that sounds the chord using the same instrument voice as the simulators. On guitar it is strummed across the strings, and on piano the notes are struck together, so you hear the chord the way you would actually play it.
Start with the open chords C, G, D, Em and Am, which between them cover a huge number of popular songs. Once you can change between them cleanly, add F and Dm, and then begin exploring 7th chords to add colour to your progressions.
Once you know a few shapes, open the Song Builder for your instrument and add those chords to a sequence. Set a tempo, choose a strumming or playing style, and loop the result so you can practise changing between the chords in time with the playback.
The piano page includes note labels for learning key names, a Mark mode for selecting and replaying specific notes, octave controls to move up and down the keyboard, and a volume control. These tools let you turn free play into focused practice on a particular scale, chord or passage.
