OT, just a little joke: In Germany we don't have a B# for what key ever.
c#/db d#/eb f#/gb g#/ab a#/b (not hb or bb)
c d e f g a h
So a b# would be a h#? Somebody mentioned that understanding this theory
does include to know the history. I agree.
For people who just want to note guitar chords, ignoring any theory
regarding to keys, in Germany it's safe to name h = h, but to name the
German b anyway bb or a#. The names of the notes are squishy, nobody can
see if written chord names are written "in German" or not, as long as
there's only a "B" but no "H". Btw. "a" means
"Am"?! There are different
writings, large and small letters, signs for same chords.
I suspect notation needs a disclaimer. We have similar issues for guitar
tabs, you'll find tons of dropped-D tuning tabs where the name of the
strings aren't added and there's no hint that it's a dropped-D tuning.
