Moo, you're much smarter than I am— literally how did Lin make Alexander Hamilton sound catchy,,, like it's literally a name,,, but it sounds so catchy when the cast sings it
Well, Serpzie I am so glad you asked!!! (and I not smarter than you but I am more than happy to use my knowledge of this very specific and niche topic to answer this)
Short answer: Lin is a genius, and that name is just inherently musical because of how you naturally say. It was made to be put to music. It has the rise and fall as you say it, which (in my brain) gives it more traction, so of course it sticks in your brain.
'Kay well first off, 'Alexander Hamilton' has so many syllables, it's lots to work with to make it catchy(As opposed to, say, 'Aaron Burr', but that one has a ton of rhymes so it works).
I don't know how Lin did it(he's a genius, idk what to tell you XD), but why it's catchy? I can try to answer that. 'Part from the entire cast singing it, which is just satisfying to hear, and that it is repeated SEVEN times in four minutes, that name specifically was just MADE to be be sung.
It already has alternating stressed and unstressed syllables, which are then paired with rising and falling notes("A" is higher than "Lex" which is lower than "An" which is higher than "Der", piano wise) played in rapid succession by a group of talented singers.
(slows down) My name is Alexander Hamilton"
Plus how the rest of the verses around it contrast:
"Alexander Hamilton!
(it slows down after this)
We are waiting in the wings for you
(Waiting in the wings for you)
You could never back down,
You never learned to take your *beat* TIIIIME!
(and then we get the speed back)
Alexander Hamilton!
(Alexander Hamilton)" and then it keeps going fastrer through "ship is in the harbour now" until break at the "we ___ with/for him" and then the rise after Burr's "shot him (shot him, shot him)"
GENIUSES, THE LOT OF THEM
