I don't know.The bass isn't as loud as in some of the pop music but I think it-- but I think that's what the tonic is.

I don't know whether it's easier for gentlemen or not because our voices are sort of in the bass, but maybe this is payback time since ladies are always singing the melody.

So we'll focus on the bass and we'll try to sing the bass, and if we find that in singing the bass our voice is not changing, probably the harmony hasn't changed.

现在把我们的注意力放到低声部上，尽量唱出低声部，如果在唱的过程中我们觉得自己的声音没有变化，那和声就很有可能没有改变。

We're not going to get into that 'cause that takes us into heavy-duty music theory, but it's--if we don't have root position then we've got some other note of the triad in the bass, and we've got some kind of chord inversion, so that's what that particular term means up there.

我们就不深究这个问题了，这是一个冗长的音乐理论，但是如果没有了原位，三和弦的低音被另一个音所替代，这就是一种和弦转位，这就是这个词在这里的意思。
