The begining where it goes ra-ra-raaa ro-ma= romomaa ga-ga ohh-la-lathe note are (all in the b flat scale!)a a e e a# a a e e a# a a e e a# c c a c ca a e e a# a a e e a# a a e e a# c c a cc
These are all low notes. The lower-cased f is a half note. Sometimes I like slurring the notes, but at the "E E" part you obviously can't. Hope this helped!
