All 4 verses on screen for singing along.
This key of Fb major is not enharmonically equivalent to E major, but rather its own distinct key with its own set of unique pitches that are a Pythagorean comma lower than they would be if in E major.
Keys outside the normal circle of fifths do exist and can be composed in and sung and played in. Because I used MuseScore 3 for this, I did not have control over the key signature. If I were in control of the key signature, it would simply have the B be doubly flat, and everything else blank. One should know if there is a double flat in the key signature, everything else is flat.
