Sure – it’s for writing multiple parts. I don’t necessarily know how many I’m going to have upfront. I’ll write a melody, and then add another staff to write a harmony part or a counter melody. This way I can keep all the writing in a single instrument, and don’t have to add and remove a bunch of piano instruments to different flows.
I should note that I use Dorico exclusively for composing / arranging / orchestrating. So this is purely for enabling my composing workflow, not typing in an existing score.
In my Dorico projects, I have a single piano for writing, and then the instruments used in the score. So I do the writing in the piano, and then copy the parts to individual instruments to orchestrate it.
I’ve tried using multiple voices in a single staff but don’t really like it – I don’t like when stacked notes are offset, it’s hard to see the individual voices, and navigation between notes doesn’t work as I expect. I really like seeing the parts on individual staves, since that’s what they ultimately will become when orchestrated.
My solution up to this point has been to create a section piano part and use divisi, and that has worked pretty well. But when I saw you can add and remove staves, that became a lot more interesting to me.
As an example, say I write a melody and decide that I want to write an even higher part (fluttering flutes or something like that). With “add staff above” I can place that new staff above the main melody and write the part there, without having to cut and paste between staves to arrange them.
you’re already well beyond what we thought people would be using the feature for
fair enough I would like to have 8-12 staves in a single instrument if possible, by adding or removing as needed. I realize that’s not typical – but it’s a cool workflow that computers make possible, that isn’t as easy to pull off on paper without some upfront planning / a bunch of rewriting.
