Problem with # notes

• Jan 4, 2021 - 13:57

I don't understand why musescore mark notes #, see upload image. First I think that problem is in Notesnames Plugin, but then I copy note to another sheet, it also marked with # (second image).

I am novice in music notation, may be I something misunderstand.

Musescore version: OS: Windows 10 (10.0), Arch.: x86_64, MuseScore version (64-bit):, revision: 465e7b6

The key signature (here: G-Major or /e-minor) demands an unadorned F to be an F#, implicitly and in evry octave, simple as that.
And MuseScore's copy/paste works on pitches, so once you copy an F#, it pastes an F#, but on a C-Major keysig, that needs the explicit #

Musically speaking, the key-signature tells you which notes are ALWAYS taken to be sharp or flat. (Unless a "natural" symbol revokes that for one measure.) This not only makes it clear "what key the song is in," but pragmatically speaking it also keeps the score from being littered with symbols! When a symbol is present, it is understood to last only to the end of the current measure. New key signatures can be inserted at any subsequent measure, usually preceded by a double bar-line.
