'With a little help from my friends' I found a way to get a little more
control over vertical spacings in my scores. The base trick is to add
something like this in a paragraph before the fist music paragraph
%% \raggedbottom
%% \parskip 3\Interligne plus 2\Interligne minus 2\Interligne
and then in the first music paragraph something like
%% \\let\interstaffsav\interstaff\def\interstaff#1{}\interstaffsav{11}\
Have a look at my typesettings, for example the madrigals by Mogens
Peders�n and their M-Tx sources published in the GMD archive to see
examples of the coding and how the result looks.
