Okay, here's what I have written down for the Laverre City theme:
DGF-GA-FG-DF--XX
"-" means I extended the note
"X" means silence
I hope that makes sense. I forget how they actually represent them in the game. Also, I think I had to change the key a bit because the Laverre City theme is a bit too high.
It was the Laverre City theme for about 3 years, but recently I changed the overall theme of my town, so I changed my town tune as well. I wrote down the notes that I used though, in case I ever want to change it back. c:
