一起来听＂圆周率＂:圆周率31位谱曲超好听

这个圆周率歌不是葱娘那首经典版本哦，而是实实在在将3.14159……这些数字对应成音符谱写的曲子~还蛮好听的哎！苦恼于数学的孩子可以在学习之余听听这首优美的钢琴曲~

WHAT does Pi sound like? Pretty good, actually.
圆周率听起来是什么效果？还真不错！

To celebrate Pi Day — the 14th day of the third month — Canadian musician Michael Blake has set the mathematical constant to a tune.
为庆祝3月14日圆周率日，作曲家Michael Blake将圆周率铺成了曲子。

Blake's music video on YouTube explains how each of the eight notes in any major scale can be assigned a numerical value — C being one, D two and so on. The same thing goes for chords.
他利用勋伯格十二平均律中所引入的半音阶概念，将半音阶与数字一一对应，即令1=C，则3=D，5=E，6=F，依此类推。

And as if that wasn't impressive enough on its own, Blake set the piece to a tempo of 157 beats per minutes, or 314 divided by two.
这段小小的曲子每分钟节拍数为157，恰为314的一半。由简单的钢琴旋律引入，中途又加入了手风琴、木琴、夏威夷四弦琴等乐器，丰富了整个旋律。

Since the success of his Pi video, Blake says he has been inundated with requests to create more music based on maths.
Blake说，已经有很多人问他再创作一些数学相关的音乐了。
