What are some internal rhymes from the play 'Hamilton' ?
Mulligan's intro lines in "Aaron Burr, Sir" and Angelica's and Burr's lines in "The Schuyler Sisters" are examples that spring to mind.
The line ending with "over four sets of corsets" is a good one. There are actually two pairs of internal rhyming here: the two words ending "-course" and then "four sets"/"corsets".
These are internal rhyming because they're rhymes that involve a word in the middle of a line.
Another good, less risqué example is Angelica's lines from "The Schuyler Sisters": "I've been reading Common Sense by Thomas Paine/ some men say that I'm intense or insane". Here, "sense" is rhyming with "intense", and both are words in the middle of lines.
Burr has internal rhyme in this song, too: "You searching for an urchin who can give you ideals?" He rhymes "searching" and "urchin" mid-line.
