Hi Fred
I think your basic problem is not appreciating how
notes should be assigned to voices. When you place the
notes in the correct voices LilyPond gives you the
alignment you seek with no overrides and no errors,
like this:
\version "2.18.0"
\new Staff = "treble"
\with { \consists "Span_arpeggio_engraver" } <<
\relative c'' {
\set Staff.connectArpeggios = ##t
\key a\major
<< { e2 \arpeggio a, }
\\ { cis,1 \arpeggio }
\\ { e4 \arpeggio e e fis8 g }
>>
}
>>
Voices 1 and 2 are not shifted by default, other
voices are, but only if there would otherwise be
a collision. The section in the manuals which
might help you with this are:
http://www.lilypond.org/doc/v2.18/Documentation/learning/real-music-example
and
http://www.lilypond.org/doc/v2.18/Documentation/notation/multiple-voices#single_002dstaff-polyphony
in particular the section on Voice order.

Subject: Still confused about horizontal shifts in NoteColumns
Running 2.18.2 under Linux, I'm looking to duplicate this:
I currently have this:
I would like to shift the first quarter note a bit to the right, about half
as much as the third, but force-hshift and the various \shiftOxxx commands have
no effect. (The stems of the quarter and half notes should be noticeably
separate.)
Snippet:
\new Staff = "treble" \with { \consists "Span_arpeggio_engraver" }
<< \relative c'' { \set Staff.connectArpeggios = ##t \key a\major
<< { e2 \arpeggio a, } \\ { \voiceOne e4 \arpeggio e \shiftOn e fis8 g } \\
{ cis,1 \arpeggio } >>
} >>
I get the usual warning -- "ignoring too many clashing note columns". The LM
says, at 4.6.1, "If and only if two or more note columns within a single Staff
context, both with stems in the same direction, occur at the same musical
moment, the values of their horizontal-shift properties are used to rank them
and the columns in the higher ranks are progessively offset to avoid collisions
of the noteheads."
So -- shouldn't the alignment I want occur automagically?
Or should "both with stems in the same direction" be "all with stems ..."?
But whole notes have no stems ... is that the problem?
Thanks!
Fred
