I’m trying to notate a key trill, which is to say a trill to a unison using a different (alternate) fingering. According to Gould, I think it should look like this:
In order to get that in Dorico, I started with an interval of 1 Unison, but that doesn’t show the auxiliary note. I had to select a trill interval of 1 Augmented, which changed the note in parenthesis to an E# and put in explicit naturals for the E on both stems. Then I had to manually hide the accidentals (including have to go to engrave mode to hide the accidental on the stem at the end of the tie).
So I got what I wanted (though only because I don’t care about playback), but I’m wondering why the unison interval doesn’t show the note in parenthesis like the other intervals – and really if that means I’m not understanding something here and should be doing this differently.
