Any frequency can't have an energy, you have to -- you don't have a continuum of frequencies that are of a certain energy, it's actually punctuated into these packets that are called photons.

任何频率不能有个能量,你必须要-对某一个能量上,你不会有连续的频率,光子实际上分立的存在。

If you allow a little bit of spacing, a little more space between your frequencies, they're a little bit farther apart, then you can move from closeness plays to spacing and you get the consonance.

如果让频率间有点间隔,给频率间多一点空间,让它们彼此远离一些,从密集的音高,转向有间距的音程,就能得到和谐音
