Hi Jennifer, it works really well if you play the chords enharmonically:
133: all flats with D-natural and A-natural, then:
F-natural
A-flat & D-flat
F-flat & A-natural
134: all flats with A-natural, then:
D-natural
A-flat & D-flat
C-natural
F-natural
F-flat & D-natural
G-natural
E-natural, F-natural
At the Largamente con calore you are in F-Major.
It’s tricky – I basically had to memorize it.
I can email you a .pdf scan of my markings if you want – just let me know your email.
Have fun!
