It sounded hip to... Everything was a tritone substitution.

听起来很时髦… … 一切都是全音替代。

Okay, let's play the tritone again.

好吧，让演奏一次全音。

And these two notes in the bass, that's a tritone interval.

低音两个音符，就是全音程。

Now, like, actively try to hear the other thing and if you can, raise your hand—okay, okay let's play the tritone again.

现在，积极尝试听到其他声音，如果可以话，举起手——好吧，好吧，让次演奏全音。
