For the questions I ask, see last in mail.
I'm trying to set the automatic beams in \time 4/4 like
a8[ a] a[ a] ..., so I'm looking at the example in
Documentation/out-www/notation.pdf (it says for version 2.15.15 on
page 1), on the bottom of page 74 to the top of page 75, section
"Setting automatic beam behavior" under "1.2.4 Beams". I added one
8'th to see what it does (voice two is of no interest in this case):
\new Staff {
\time 7/8
\set Staff.beatStructure = #'(2 3 2)
% \time 4/4
% \set Staff.beatStructure = #'(1 1 1 1)
<<
\new Voice = one {
\relative c'' {
a8 a a a a a a
% a
}
}
%{
\new Voice = two {
\relative c' {
\voiceTwo
\set Voice.beatStructure = #'(1 3 3)
f8 f f f f f f
}
}
%}
>>
}
In 7/8 it works as advertized, but when changing into 4/4 I get
no change from the default.
The first sentence of the section "Setting automatic beam behavior"
says:
[1] In most instances, automatic beams will end at the end of a beat.
This sentence is not true for one of the most common time sig. 4/4,
and it tricks me to believe
\time 4/4
\set Voice.beatStructure = #'(1 1 1 1)
will work for 8'ths, which it won't.
I do find:
(define-public default-time-signature-settings
'(
...
((4 . 4) .
((beamExceptions . ((end . (((1 . 8) . (4 4)) ; 1/8 notes half
measure
((1 . 12) . (3 3 3 3)))))))) ;Anything
shorter by beat
...
in scm/time-signature-settings.scm
And after some false starts I found out I had to do:
\set Timing.beamExceptions = #'((end . ( )))
Then I also found out I cannot set it like:
\score {
\new ChoirStaff <<
\set Timing.beamExceptions = #'((end . ( )))
...
I have to put it after every damn \time sig.
///
* If I set a beatStructure, why isn't the exceptions cleared?
* And why doesn't that sentence [1] say "In unusal time sigs. the
beatStructure will solve your needs, but for the most common
things, you will have to struggle through the section about
beamExceptions below." ?
* How do I clear the default behaviour set in
default-time-signature-settings?
