A song sits inside a set of notes that belong together. You can think of off as one step outside that set: the sound has slipped a little above or below where it should be, and the ear catches it before the mind can name it. That small slip is the whole word. Everything else it does is the same slip moved somewhere else — a joke that lands just outside the mood of the room.
一首歌會待在一組彼此合得來的音裡面。可以把 off 想成「踏出那一組一步」：聲音稍微高了或低了一點，耳朵先抓到，腦袋還說不出哪裡怪。這個小小的偏離就是這個字的全部。它其他的用法，其實都是把同一個偏離換了地方——一句笑話剛好落在現場氣氛的外面一點點。
