What we've done is taken this pitch and played it all the way down an octave below it so we're actually getting back to this configuration of the pitch right next to it, and we could--then of course we could go down one more step and we would get the octave, which is a duplication of two-to-one.

我们所做的是固定一个音高，向下一路弹奏一个八度,所以事实上我们又回到了与这个固定音高相邻的音上，我们当然也可以向下再弹一组，然后得到这个八度，这其实就是两个八度对一个八度的重复。

If I play the D above it, it's dissonant, the D below it,it's dissonant, but let's say I go down to the A below it, allowing a little separation between the two pitches now.

如果我弹它上方的D音，这个声音是不和谐的，它下方的D音，不和谐，但是如果我弹它下方的A音，让这两个音高之间产生一点空隙。
