This is the tonic solfa of the USA national anthem. You can derive the chord progression from the solfa notation too.
s m d m s d O say can you see
m’ r d m fe s by the dawn’s early light
s s m’ r d t What so proudly we hailed
l t d d s m-d at the twilight’s last gleaming
s m d m s d Whose broad stripes and bright stars
m’ r d m fe s through the perilous fight
s s m’ r d t O’er the ramparts we watched
l t d d s m-d were so gallantly streaming
m’ m’ m’ f’ s’ s’ And the rockets’ red glare
f m r r f f f m the bombs bursting in air, Gave proof
r d t l t d m fe s through the night that our flag was still there
s d d d t l l – l r m f m r d d t O say does that star-span-gled banner yet wave
s s d r m f s O’er the land of the free
d r m f r d and the home of the brave
O say can you see,
by the dawn’s early light,
What so proudly we hailed
at the twilight’s last gleaming,
Whose broad stripes and bright stars
through the perilous fight,
O’er the ramparts we watched,
were so gallantly streaming?
And the rockets’ red glare,
the bombs bursting in air, Gave proof
through the night that our flag was still there;
O say does that star-span-gled banner yet wave
O’er the land of the free
and the home of the brave?
