[TeX-Music] Vertical distribution of systems.
I have a piano score with only 4 systems. I do not like the vertical
distribution I obtain because the first and last systems are stuck to the
vertical boundaries of the page.
Instead, I would like the space above the first system and below the last
system to be half the space between systems. How can I do this without putting
two ugly \vspace's in my source?
\input musixtex
\instrumentnumber1\setstaffs12\setclef1{\bass\treble}
%\vskip2cm
\startpiece
\NOtes\qa{HKNH}|\qa{hjec}\en\bar\NOtes\qa{HKNH}|\qa{hjgc}\en\bar%
\NOtes\qa{HKNH}|\qa{hjlc}\en\bar\NOtes\qa{HKNH}|\qa{hjoc}\en\bar%

\NOtes\qa{HKNH}|\qa{hjec}\en
\linegoal4%
\Stoppiece
%\vskip2cm
\eject
\end
Incidentally the first \vskip does not do its job.

Your example below just includes 2cm for the \vskip's. Shouldn't it be
.5\somemusixtexparameter? (it's early - I can't remember what the \dimen or
\skip for that is called).

I may be corrected with a very clever alternate solution, but I think you're
hitting one of TeX's few brick walls - while it's very clever at making
paragraphs (and MusixTeX is very clever at making staves) neither is as clever
when it comes to making pages. The reason is a combination of the fact that in
the eighties and nineties it wasn't possible to use the same of level of
algorithm over entire documents as it was over paragraphs because of memory
constraints on the computer and also because pagination often just has to be
tweaked by a human anyway in order to look really nice (for example, TeX's
paragraphing algorithm produces the actual optimal result but its pagination
algorithm does not). I find this often that means that TeX's facilities for
doing something automatic with pagination are therefore a bit limited compared
with some other areas of TeX. You could possibly come up with a very hairy
\output routine to do this.
\input musixtex
\instrumentnumber1\setstaffs12\setclef1{\bass\treble}
%\vskip2cm
\startpiece
\NOtes\qa{HKNH}|\qa{hjec}\en\bar\NOtes\qa{HKNH}|\qa{hjgc}\en\bar%
\NOtes\qa{HKNH}|\qa{hjlc}\en\bar\NOtes\qa{HKNH}|\qa{hjoc}\en\bar%
\NOtes\qa{HKNH}|\qa{hmjc}\en\bar\NOtes\qa{HKNH}|\qa{hcec}\en\bar%
\NOtes\qa{HKNH}|\qa{hmjc}\en\bar\NOtes\qa{HKNH}|\qa{hjec}\en\bar%

\NOtes\qa{HKNH}|\qa{hjec}\en
\linegoal4%
\Stoppiece
%\vskip2cm
\eject
\end
Incidentally the first \vskip does not do its job.
At the moment your sample ends unusually - if you look at the definition of
\bye then you'll see that it has a \vfill in it. There is some glue at the end
of the score (probably a stray \parskip as that by default has 1pt of
stretchability) which has been over-stretched to the bottom of the page because
you omitted the \vfill. If I change the top \vskip to \leavevmode\vskip2cm and
the last one to \vskip 2cm plus 1fill then I get something closer to what you
intended.
See Chapter 15 of the TeX book (but don't do that first thing in the morning -
it's a very hairy chapter!) - TeX removes glue at page break boundaries and the
start of the document is considered a page boundary. You need to insert a
\leavevmode before the \vskip (the \leavevmode instruction temporarily forces
TeX into paragraphing mode which means that it doesn't delete the \vskip).
HTH,
David

that's what the \leavevmode is for. (it's not the *right* thing to do,
but since my brain is only just waking up, it'll do.)
\hskip at the start of a line doesn't work either...

Simply the need for my calculating the half of the distance between systems
before I know this distance! IMO trial-and-error is even uglier!
instead:
\leavevmode\vskip0pt plus2fill
\lineskip0pt plus1fill

This gives too big a top space. Could you please explain how I can adjust
the spaces?

I can work around by saying \centerline{~} before this \vskip.

the same thing (in effect) as \null does: an invisible hbox on the main
vertical list. \leavevmode actually starts a line, though it doesn't
seem to matter here.

That's what I was referring to! A hairy \output routine would break \box255 up
and find the \skip's but analysing the \output of \vsplit is not fun.
But TeX hacking to one side, I'm still not entirely clear what you're after
in layout terms - doesn't MusiXTeX already insert a *known* amount of space
between systems already (\staffbotmarg and \stafftopmarg - the computed
value \systemheight may be useful in calculations too)?
\staffbotmarg and \stafftopmarg need an argument (cm, in, \Interligne or
other). Like \vskip, they won't calculate this argument for me!
AFAIK MusiXTeX puts between systems the space it thinks is clever. If a system
has a high, high symbol it adapts these spaces. Replace a \qa somewhere in the
middle of my example with \qa{hce''z} and you will see what I mean.

No, \staffbotmarg and \stafftopmarg are both \dimen's... you can read them. Try
saying \showthe\staffbotmarg in your source file. \Interligne is also a \dimen
(but one you aren't supposed to touch).
When you say \staffbotmarg2cm you are simply setting the value of the \dimen
(same with 3\Interligne - TeX offers free multiplication when assigning to a
\dimen so \staffbotmarg3\Interligne means multiply \Interligne by 3 and assign
the result to \staffbotmarg). It would be clearer if, as I do in my sources,
people actually included the optional equals sign. \staffbotmarg3\Interligne
can also be written \staffbotmarg=3\Interligne which would stop people thinking
it was a macro... one of the (few) mistakes of TeX's grammar (and an artefact
of a time when 100Kb and less was actually a user's storage quota!)
\staffbotmarg and \stafftopmarg are certainly correctly defined (at 15pt) just
before \startpiece.
AFAIK MusiXTeX puts between systems the space it thinks is clever. If a
system has a high, high symbol it adapts these spaces. Replace a \qa
somewhere in the middle of my example with \qa{hce''z} and you will see
what I mean.
And you want to take that into account?? That would create variable top-line
spacing in your score which sounds like an odd idea. Those parameters are also
available, line-by-line (see the MusiXTeX manual) but you would have to code
macros to capture them yourself. Incidentally, why do you want fixed spacing at
the bottom of the score?

Aha - I finally understand the problem (sorry - being slow). What's actually going on is an underfull \vbox which I'd failed to notice before in the transcript before. TeX expands stretchable glue infinitely in an underfull box (rantit is the single most annoying thing I find about TeX and have had to work-around that illogical decision on many occasions.../rant) How does putting \musicparskip before \startpiece and \vskip\parskip before \eject (and no other \vskip's) look to you?

The bottom is acceptable, but I see no addtional space on the top. But perharps you're pointing out the right direction. Does MusiXTeX modify \parskip and \musicparskip when it shares the spacing? Could another ordering of \musicparskip, \startpiece, \stoppiece, \parskip be the solution? Can I divide \parskip ou \musicparskip by 2? In this thread http://www.mail-archive.com/icking-music-archive.org-tex-music@mailman.nfit.au.dk/msg01906.html there was no reply to my question about the usefulness of \musicparskip.

[TeX-Music] Space between pagenumber and the first stave
May be my question is related to what just is discussed. I use M-Tx for my typesetting. If the last page consists of fewer staves than possible the space between the pagenumber and the first staff is smaller than on full pages. Any suggestion?
