Moving on. Measure 9 is a bit of a relief.
The harmony is E Major, with a slight shift to e minor as you move to measure 10.
I love this piece because the shifting harmonies remind me of the shifting colors of a vibrant sunrise or sunset.
Color changes are significant, but it is difficult to pinpoint the exact place where bright salmon pink changed to a velvety midnight blue.
Beethoven often changed harmonies by moving one key.
