Global accidental, how to?

• Apr 25, 2014 - 16:53

Working with a lever harp piece. It's "technically" in the key of C, with the exception that every G is sharped. The Sibelius app that the originator uses allows for placing a G# as text in the very first measure , right after the key signature. I am going to assume that when she plays it back, it plays it correctly.
I 'could' either hand correct each and every G with the accidental, or change the key sig to A Major and then un-sharp all of the C's and F's. Neither sounds like a nice , simple process - giving me an easy to read score.
So... is there a method to globally force ( like a lever change ) an accidental and have it play back correctly?
Thanks so very much for the great app.

If I am understanding correctly, you want a key signature of C (no sharps or flats) but an "effective" key signature that has G# (only). So notated "C D E F G A B C" (with no accidentals) will play back as "C D E F G# A B C".

if so, then I don't know of an automatic way to get this. You can create custom key signatures, but they are for show only - they don't affect playback. But if the piece has no other accidentals (not unlikely according to my understand?), you simply hide the #'s on the G's. Right click one, select all similar, right click again, set invisible.

You have the concept - actually it's a common phenomenon in folk ( ie levered ) harp music. I will try the 'hide all similar' within the next hour and see how that plays out ( no pun intended ). This will mean, however, that I will have to go through the entire piece, sharp all of the G's, then perform the hide and finally add the staff text to make it levered harp music.
[ edit ] : went back to my Alfred's and figured out that what is written/played is in Dmaj Lydian mode. Thus the need for the sharped G only in an otherwise C major key ]
[edit edit] : Nope, it's not D Major at all, it's really C major with all the G's sharped - none of the modes fit, nor any of the normal scales. Oy! ]

How was this score created in MuseScore? Was it exported from Sibelius to to MusicXML and then imported it into MuseScore? If so, then this is probably a limitation of that facility - either Sibelius' export or MuseScore's import, more more likely both, are not handling non-standard key signatures correctly (assuming MusicXML even defines a way to do this at all).

Assuming you typed the score by hand, then I'd say this is simply a case where you should have entered the sharps yourself during note entry, since those *are* in fact G#'s. And since you didn't do it then, you will indeed need to do it now. This is the sort of thing where I suppose a plugin might be able to automate the process, if you are up for some programming or no a lever harpist who is.

My wife's harp instructor/composer pub'd a book with this song in it. I have it in paper, scanned to PDF, 'PDF Convert' to .mscz as well as the composer's export of Sibelius to .mid . I am doing the entry into MuseScore by hand/keyboard and that is when I found the oddity of global accidentals. Mostly just hoping that it was yet another MuseScore trick that I'd missed along the way. Thanks Marc, for being so responsive. al

Doesn't usually have a key signature. Just have to bite the bullet and sharpen the G's. Or write a Plugin to do it (find every occurrence of the pitches corresponding to G, get their length, +1 to pitch, re-write etc.) - on balance, just sharpen the G's.

You can enter a sharp symbol manually on the G line. You can then select all sharps (not just the G sharps, though) and make them invisible. Don't just delete them as that will turn all the Gs back to naturals.
