Re: Tempo Alignment Questions

[Shane Brandes]

\override Score.MetronomeMark.extra-offset = #'(x . -y)  that will do
it you will have to iterate a few guesses to get what you want.

Tempo Alignment Questions

[Jay Anderson]

I'm unable to find them at the moment, but I've seen threads discussing
general overrides for tempo marks to make them work better (e.g. avoid
stacking, better horizontal alignment with other objects). What are the
current recommend overrides that you use to get better tempo behavior? The
suggestion from Gould is:
- Align with the time signature
- If no time signature then align with the first notation element (that's
not the starting clef or key signature)

Here are some things I'm looking to solve:

(1) Align with repeat sign at the beginning of a system. I haven't found
the right overrides to make that work.

=
\version "2.19.80"
\score {
  \new Staff \transpose c c' {
c1 | \break

%RehearsalMarks align where the tempo should in this case
\override Score.RehearsalMark.self-alignment-X = #LEFT
\mark "RehearsalMark"

%Not sure how to make MetronomeMarks align. Here's what I've tried:
\override Score.MetronomeMark.break-align-symbols = #'(staff-bar)
\override Score.MetronomeMark.non-break-align-symbols = #'()
\tempo "MetronomeMark"

\repeat volta 2 { c1 |}
  }
}
=

(2) Align with accidentals. The default lilypond behavior is to align with
the notehead. Like the above I haven't found the right overrides to make
this work.

=
\score {
  \new Staff \transpose c c' {
cis1 |
%Not sure how to make MetronomeMarks align. Here's what I've tried:
\override Score.MetronomeMark.non-break-align-symbols =
#'(accidental-interface)
\tempo "Accidental Alignment"

cis1 |
  }
}
=

(3) Alignment with multimeasure rests. I haven't found any definitive
source for how these should behave. It isn't addressed directly in Gould
though there are some examples on page 565 where they appear to be just to
the left of the bar line. Lilypond does this mostly, but it leaves more
horizontal space between the bar line and the start of the tempo than I'd
like.

\override Score.MetronomeMark.non-break-align-symbols =
#'(paper-column-interface multi-measure-rest-interface)

The above is very close except after a break the tempo indication left
aligns with the left edge of the system instead of right after the clef.
I'm not sure how to fix that.

=
\score {
  \new Staff \transpose c c' {
\compressFullBarRests
\markLengthOn
\override Score.MetronomeMark.non-break-align-symbols =
#'(paper-column-interface multi-measure-rest-interface)
\tempo "Somewhat long tempo"
R1*20 |
% Align to bar line
\tempo "Another long tempo"
c1 | \noBreak
R1*20 |
%Misaligned after break
\tempo "Yet another long tempo"
R1*20 |
\tempo "Final long tempo"
R1*20 |
\markLengthOff
  }
}
=

In conjunction with the above, to nudge it slight to the left of the bar
line with multi measure rests the override below seems to work well and I
like it better than directly aligning with the bar.

=
#(define (is-bar-aligned grob)
  (and (grob::has-interface grob 'break-aligned-interface)
(eqv? 'staff-bar (ly:grob-property grob 'break-align-symbol

#(define (callback mm)
  (let ((parent (ly:grob-parent mm X)))
(if (is-bar-aligned parent)
  '(1 . 0)
  '(0 . 0

...

\override Score.MetronomeMark.extra-offset = #callback
=

(4) Alignment after rehearsal marks. My preference here would be to have
the rehearsal mark followed by tempo mark instead of stacking. Most of the
time this isn't a big problem. However when music gets a bit compressed
they stack (even using \markLengthOn). Also if I manage to make the above
(3) work for alignment with multimeasure rests this will also occur. This
would be worth thinking about after the above.

Any suggestions for the above would be welcome. Thanks.

I still think this is amazing (thanks again!), but… My instinct/intuition says 
that the Y axis of the extra-offset should work like it does for every other 
grob, i.e., + goes UP the page, and - goes down. Right now, it’s the opposite. 
Just a thought!

I'd consider being the mentor for this project.

I agree that, before it is GSoC-consumbale, I think there needs to be some
discussion about how it fits together, and break it into parts, each
appropriate for a project.

I'm in the midst of writing up some notes and suggestions, but I figured
I'd mention my interest first.

Hopefully I will try someday and make a post (on the lilypondblog.org
if I could set myself an account) for my setup which I think is quite
powerful for, easy to setup, complex chorus and full orchestra,
*multiple score* work.

The multiple score support was lacking in my setup but I need to make
it work ASAP.
It got me going for the last year and currently generates multiples
editions (letter, tablet, huge, kindle, etc) for all parts in the
orchestra for a small setup time.

Thank you very much Thomas.

I note that all the Lyric improvements are no longer listed as a GSoC project. 
What's the reason there?

In addition to the stuff that Janek was actively working on — now quite a while 
ago — there was a flurry of discussion not too long about about whether 
LyricText could have some "fixed versus flexible" springs-and-rods 
mechanism(s), so that lyrics don't always distort note-spacing. I think this 
project would easily fill up three months of full-time work, but could also be 
modularized.

That would be the project I most want to see completed (or at least 
significantly tackled/advanced).

Thanks,
Kieren.

Well, we do have a subsection "Guile predicates", with a single entry:
"hash-table?"
Maybe we should add "module?" there.

Iirc it's not that long possible to assign a header to a variable. But
now we should be prepared that users will take the opportunity to use
it in functions, like you did.
So, yes, let's document it, imho.

Btw, if I'm not mistaken, "module?" is not even listed in the
guile-manual, neither guile-1.8 nor guile-2.2.3

I'm not quite sure how to "unfold" the score if that makes any sense.
I am using (display (car score-list)) just to figure out what is going on.

Good day

It does work! Thank you very much.

FTR, At first I tried "ly:module?" as a predicate.
Also, I did look for any "module" predicate in the predefined type
predicates documentation page.
The "module?" is not listed in this page.
^ Should I notify the bug list?

Good day
