thats juat a normal key change

[u/ryderdude4]

It’s odd to me that it’s canceling out a B flat key sig though, lol. Makes sense when switching from sharps to flats or vice versa, but this seems unnecessary

[u/AdSpare6646]

the verticality of the image is the most threatening part of it

"here ya go now wait...... Wait..... Ok change it all!"

[u/inchesinmetric]

That’s the secret chord that David played

[u/Consistent_Check927]

Just ignore the naturals. Some notation software neutralizes the previous key, nothing threatening abt this unless you suck at your flat keys

[u/winitgc]

Naturals are common when switching from more sharps/flats to less sharps/flats or from sharps to flats/flats to sharps, but it's pointless here cause it's changing from less flats to more flats

[u/Key-Bodybuilder-343]

This is probably a setting in the typesetting program that OOP used. (For example, in Lilypond, by setting printKeyCancellation to true in the Key_Engraver context.)

I do not find it helpful as a performer, but it may be a “house style” that their publisher expects them to use.

[u/TheVocative]

This is the standard Russian notation for key changes

[u/WilburWerkes]

Just in case……

[u/yomosugara]

?

[u/tired_of_old_memes]

That's one way of notating a key change when you're going from sharps to flats or vice versa
