Hello again,
So, my latest attempt to put proper analysis brackets underneath both
staves is to use an extra invisible RhythmicStaff like this:
\context RhythmicStaff \with {
\remove "Bar_engraver"
\remove "Staff_symbol_engraver"
\remove "Time_signature_engraver"
\remove "Rest_engraver"
\consists "Horizontal_bracket_engraver"
} {
r16\startGroup\startGroup\startGroup r r r\stopGroup
r\startGroup r r r\stopGroup\stopGroup
r\startGroup\startGroup r r r\stopGroup
r\startGroup r r r\stopGroup\stopGroup\stopGroup
}
However, the \remove "Rest_engraver" seems to be having no effect. Nor
does trying to remove note head and stem engravers when using notes
instead of rests.
Could somebody please tell me what I'm doing wrong?
Also, even if it worked, this would definitely be a sub-optimal solution
from a spacing point of view, so I'd still like to know if there's a
better way (as I start to glimpse the power of tinkering with lower
levels of lilypond, I think there must be!)
I would be most grateful for any response - I'd love to have more time
to play, but I've got to hand in a dissertation (with this analysis in
it) in two week's time!
Thanks,
Hamish

Hi,
As this is my first post, I'd like to say thank you very much to the
developers for creating Lilypond -- I've just yesterday started having
to typeset music within LaTeX documents; I had a quick play with
MusiXTeX, but thankfully shortly afterwards found Lilypond and
immediately became very glad of its existence!
My query is about analysis brackets. I'm trying to show nested
metrical structure in Bach's Prelude No. 1 from the Well-Tempered
Clavier (see source code below). I want two brackets per bar, then
brackets round pairs of those, etc. I'm using the PianoStaff so I've
got two staves. If I put the groups around notes in the top stave. the
brackets appear between the staves, wheras I want them either below or
above both staves. If I put the groups around the notes in the bottom
stave, the brackets don't stretch far enough (because the notes in the
bottom stave are longer - but I want the brackets effectively to cover
both staves). I tried adding eight s16 invisible rests to the chord at
the bottom but the brackets would still only stretch as far as the
visible notes.
Is there any way either to have the brackets upside down above the top
stave, or to have them cover more of the bottom stave?
Whilst we're here, can I use the square bracket shorthand for
\startGroup and \stopGroup without changing the time signature? I
tried it out, but of course it just extended the beams over the rest.
Also, how might I use the triangular grouping engraver?
Many thanks in advance,
Hamish
