How should I write the layout in def-score to notate a four-part chorale on two piano systems, see attachment?

(The layout documentation has no explicit description about, how to notate more than one voice in one system.)

Thanks for help.
Achim

With voice notation like: (z^q c4 q d4) but I don't know where is the documentation in the system... Janusz ?

Can't you use merge-voices?

From the doc:

(setf voice1 '(w c2)

voice2 '(h c4 d4)

voice3 '(q g5 g5 g5 g5))

(merge-voices voice1 voice2 voice3)

=>(z^w c2 z^h c4 q g5 g5 z^h d4 q g5 g5)

You don't merge the voices, you do all this in layout.

Indeed, possible with layout directly.

This was actually my question: How do I do it in layout?
The documentation is not clear about it. I remember Janusz implemented it for one of my pieces, but this code is not working anymore.

In the docs there is an example like this:

(piano-layout '(right-hand-1 right-hand-2) 'left-hand))

I tried this, but it didn't work:

(piano-layout '(right-hand-1 right-hand-2) '(left-hand-1 left-hand-2))

Could you give me a hint how to write this correctly?

Thanks, Achim

Thanks a lot. I didn't know that this is only working with the piano-solo-layout.

Best, Achim

Works with piano-layout as well. This method can be applied to any instrument if you need to create 2 voice instrument.
