When I was a kid, I loved the Mathemagic book [1] IIRC this was one of the tricks described in the book. [1] https://www.amazon.com/Mathemagic-Raymond-Blum/dp/0806983558
人们有时会对此嗤之以鼻，但我怎么推荐《 Donald Duck in Mathemagic Land 》都不为过：http://www.youtube.com/watch?v=iEVGQKwKeCc 他们跳过了三和弦与现代（西方）大调音阶之间几个世纪的演变和调整，但它提供了一个很棒的视觉答案……
People sometimes guffaw at this, but I can't recommend Donald Duck in Mathemagic Land enough: http://www.youtube.com/watch?v=iEVGQKwKeCc They skip over several centuries of shifting and tweaking between the triad and the modern (western) major scale, but it's a great visual answer…
