How to change the key in the middle of a bar (measure)

• Jan 23, 2025 - 17:46

I've searched the handbook but couldn't find how to change the key signature within a score. Of course I know how to make it between two bars, but the piece I'm currently engraving, require the key to be changed in the middle of a bar, see attached picture.

How is this done?

NB, the time signature is 6/8.

Thanks. The old material I used was published by Belwin and Mills Publishing Corp. which I never heard about, but when I checked an even older Schlesinger (Berlin) publication, I see that they make the key change between two measures so I think I trust that solution better

Sorry, I read the old and difficult to read score incorrect4ly. In fact, they also change the key in the middle of the measure.
Also, what's written in the handbook, i.e.
"Note: It is also possible, though uncommon, to add a key-signature mid measure by selecting a note then clicking a palette key signature, or dragging the key signature to a note."
does not work.

It doesn't make a difference if you click a note, a rest or drag the key where you want it. It always jump to a beginning of a measure. Somewhere midway through a measure does not4 exist. For me as a software and signal processing engineer I would call the quantisation is only whole measures or am I wrong.

Well, you could add local key signatures to all the staves.

I am surprised that the handbook instructions don't work. It's a long time since I had to add a mid-bar key signature but I don't recall any problems. Tomorrow, when I get back to my PC I will try again.

One thought occurs to me, are you trying to add the key signature at a point where a note is sustaining in another stave? If so, you probably need to split the sustaining note and use a tie so that the key signature has somewhere to go that is not the middle of a note.

Yes, the new barline must be made invisible. This is how you put a key change (or a repeat) in the middle of a measure.

It will not cause corruption problems. This sort of measure causes problems only when set up incorrectly (e.g., when the measure is imported from .MID or .PDF or another format). By Splitting the measure or by explicitly changing its Actual Duration in the Measure Properties dialog, you are explicitly setting it up correctly to have fewer or more beats than the time signature shows.
