So they not only lowered the string, they gave the squirrel a step stool mug.

所以他们不仅放下绳子，还给了松鼠一个踏凳杯子。

You can hear a big range in the higher, the higher string is very thin. And then a lower string is quite fat, so it makes that deeper richer sound, because it vibrates at a slower speed.

你可以在更高的地方听到很大的范围， 更高的弦很细。 然后较低的琴弦非常粗，所以它会发出更深沉更丰富的声音， 因为它以更慢的速度振动。
