In my current project, I'm trying as far as possible to replicate the
spirit of the original 18th century publication, in which a key change has
a clef printed, and both after the bar line. In one piece, there's a segno
in the middle of a bar, with such a key change. In standard Lilypond, this
micro-example shows that the printed clef comes before the bar line (I've
left out the segno marker and all other markers outside the score):
global = {
\language english
\clef treble
\time 4/4
}
\relative c' {\key c \major c4 d e fs | g a \bar "||" \set Staff.forceClef
= ##t \key c \minor bf c | bf af g f | ef d c2 }
But modern practice is to put the clef before the double bar, and the key
change afterwards. I want the clef to come after that double bar.
According to the documentation, this can be changed with "break-alignment",
in particular with:
\override Score.BreakAlignment #'break-align-orders =
#(make-vector 3 '(span-bar
breathing-sign
staff-bar
key
clef
time-signature))
However, in the mini example just given above, adding that override in the
global declaration has no effect. I tried changing the order of "key" and
"clef" in the override, again with no effect. (When I tried his in a
larger piece, the key change was printed on the bar-line!)
Is there any way I can notate a key change, at a segno with an extra bar
line, in order: bar line, clef, key ?
Many thanks,
Alasdair
