Cool idea!  You’re thinking is exactly how I’d do it.
I'd copy and paste the naturalizeMusic function from the doc and adapt it to 
return a list of pitch classes from the music.
Then, you can flatten the returned list (if need be) and do a map on the list 
with a lambda function that takes a numeric pitch class and returns a markup 
with a note name.
