As is common, I use the octave transposing treble clef for my guitar music. It works well and plays back correctly. I have, however, discovered that, if I change the clef – as I might for a cue – the music that was in the transposing treble clef ends up an octave too high in the new clef. This is an error that should be corrected. At the moment, I’m fixing it in the properties panel, but i shouldn’t have to. Thanks!
I’m not sure exactly what you’re saying here, John. The guitar is written an octave higher than it sounds, regardless of which clef you use.
This is because the octave transposition is built-in to the Guitar instrument itself, regardless of the clef used. Also, Dorico behaves in one of two ways: either ignoring octave clefs (the default), or ‘respecting’ them, so that they affect the pitch. You can switch this in Notation Options > Clefs.
If you want to use other clefs with the Guitar, then you’ll have to create a Guitar instrument in the Instrument Editor that doesn’t transpose; then set Dorico to “respect” the octave. That will work for other clefs, or for cues – but not for your ‘normal’ guitar clef, which you’ll need to adjust!
So, swings and roundabouts. Essentially, you’ll have to make the adjustment somewhere, however you do it.
Normally, when you use an octave-transposing treble clef, it’s not. This is normal classical guitar notation, not universal, but also not weird.
If you want to indicate the octave shift with a clef, and not have it ‘assumed’ in the instrument; then you’ll need to create a new guitar instrument in the Instrument Editor that doesn’t transpose, and which uses the relevant ottava clef by default. (You may also need to set the Notation Options for clefs to respect the octave.)
See this similar post about Tenors. Dorico already comes with two Tenor “instruments”: one that assumes the octave shift, and one that doesn’t. I suppose there’s an argument that it ought to come with similar instruments for guitar. But it’s easy enough to make your own.
