Contains an example of internal rhyme?

It's a rhyme that happens in the middle of a line, rather than at the end. Here's a couplet from a Sondheim lyric:

And if I wanted too much, was that such a mistake at the time?

You never wanted enough. All right, tough, I don't make that a crime.

Notice the placements of much-such, enough-tough and mistake-make as well as the conventional time-crime.
