I have a query regarding Transepose.
It should be in C major as indicated, so why is there a flat?
How can this be resolved?
It’s probably something to do with the instrument’s transposition.
As usual, upload a file and we can tell you.
As @DanielMuzMurray indicates, it has to do with the instrument’s transposition. You’ve got clarinets in A, so when the concert key is C major, they display Eb major. You can see that when you switch to clarinets in C, the flats disappear.
Isn’t it about adding C major?
When adding a key signature, it needs to be the concert pitch key (the actual sounding key signature). The Clarinet in A sounds 3 semitones lower than its written key signature, which means that its written key signature needs to be that of a key which is 3 semitones higher than the concert pitch one. So, concert pitch C major will be E flat major for an A Clarinet. Because I sometimes get this round the wrong way, I now always enter a key signature when the layout is set to Concert Pitch.
I’m not sure what you’re asking. It looks like you have transposing clarinets in A, and at the green box you’re changing the key to concert C major. That’s Eb for the transposing clarinets.
Don’t change manually the key signatures for transposing instruments, Dorico handles this automatically!
If you display your score in Concert Pitch, transposing instruments will have the same key signature as the other ones, if you display it in Transposed Pitch, they’ll have their transposed KS, as explained above.
Published score are generally in transposed pitch, like here (A minor is the key signature, so the piano is displayed in A minor, and the A clarinet in C minor)
What’s your goal? Do you need to copy this score exactly? If so, the clarinet is in C, so it doesn’t transpose, as you can see.
If you switch to a clarinet in A, Dorico will show one flat (F major) instead of the two sharps (D major) — assuming you’re in transposed pitch.
Once again you don’t have to change the Key Signature yourself!
Which one? The one in this post? That shows a piece in D major, with 2 sharps. The clarinets are in Do (C), so they don’t transpose and also have 2 sharps.
