Hello:
Scarlatti "looks" simple but of course is not. I'm using a Longo
edition to create a basic score which I will edit (hopefully) from
the Kirkpatrick facsimile into a performing edition.
I have this specific problem for the moment which wil lead to another
question about schemes.
----------- Sscoe Snip ----------
\version 2.11.27
\include "english.ly"
Sonata_Emajor_K530.ly
\version "2.10.25"
upper = \relative c'' {
\clef treble
\key e \major
\time 3/4
e b fs r4 r8 \bar "||" % Bar 20
\key e \minor r8 b''8 \grace a16 g8 fs e d | % Bar 21
\override Staff.NoteCollision # merge-differently-dotted = ##t
<< { c,2 \stemUp a'4 | } >> \\ % bar 22
\grace b16 c2. |
}
lower = \relative c {
\clef bass
\key e \major
\time 3/4
r4 r8 e' b fs \bar "||" % Bar 20
\key e \minor e4 r4 r | % Bar 21
r8 a''8 fs8 ds cs b | % Bar 22
}
\score {
\new PianoStaff <<
\set PianoStaff.instrumentName = "Piano "
\new Staff = "upper" \upper
\new Staff = "lower" \lower
>>
\layout { }
\midi { }
}
------------------ end Score -------------
This renders, but not as it is supposed to. The right hand should have
a second voice joining and the dotted half c and half note c should be
the same note with stems going both up and down. Instead it renders as
if it were new bars of consecutive score,
I also get this Guile error: error:
--------- snip -----
GUILE signaled an error for the expression beginning here
\override Staff.NoteCollision #
merge-differently-dotted = ##t
Unbound variable: merge-differently-dotted
----- snip ----
The line breeaks in the error are as they appear when I invoke
lilypond in the shell.
First, I think I do no quite undersand the override and collision and
Second, have I added the new polyphonic voice correctly?
Do I need to put something in the scheme definitions about these new
polyphonic bits? The occur with regularity in this peice but are
transitory in nature. They last a few measures then the voice simply
disappears as is not uncommon in piano scores.
Cheers,
David
