Greetings Paul, It would be best to see a code example. However, I have done this several times. You need to give the lower staff of the first piano a name, and then tell that temporary staff to be placed under that named context. Here is a template for just one piano, where staves are added above and below:
\score { \new PianoStaff << \new Staff = up { \relative c' { MUSIC << \new Voice { \oneVoice MORE MUSIC } \new Staff \with { alignAboveContext = #"up" } { ADDED STAFF } >> } } \new Staff = down { \relative c' { MUSIC << \new Voice { \oneVoice MORE MUSIC } \new Staff \with { alignBelowContext = #"down" } { ADDED STAFF } >> } } >> } hth, Hwaen Ch'uqi On 9/4/21, Paul Hodges <p...@cassland.org> wrote: > I can't find anything bearing on this, I'm afraid. > > I am writing out a piece for two pianos; so there is a grand score > containing two piano scores.
