I'm learning Gymnopedie no 1 from the Faber-music Piano Anthology but I'm confused about the key signature of B-flat. All of the B-flats within the piece are written as a natural and there's an abundance of F# and C# accidentals. Why not just write the key signature in D major? Why is a B-flat used instead? A detailed explanation would be greatly appreciated, thank you!
I did a little analysis of the piece here: https://music.stackexchange.com/a/122476/23919
If it is not a mistake, I think maybe the Faber edition made a choice to notate it in
D minor, because the piece ends in
Personally, I wouldn't change the key signature for that, because Satie used the key signature of two sharps, and there is no reason to think he was making some twisted musical joke via the key signature in this case.
Seems like a mistake.
All the versions of Satie's Gymnopedie No. 1 on IMSLP (including a manuscript) have two sharps in the key signature.
Maybe at some point someone got D minor and D major mixed up?
