The procedure named normalshapemediumseriesnormalshapemediumseries\everystaff is executed each time a new system is typed. It is normally void, but it can be defined (simply by normalshapemediumseries\ def normalshapemediumseriesnormalshapemediumseries\everystaff{ ...} ) to tell MusicTEX to post anything reasonable at the beginning of each system. It was used in the example NWIDOR to post octaviation dashed lines at the end of the piece.
The procedure named
normalshapemediumseriesnormalshapemediumseries\atnextline, normally void, is executed at the
next computed (through
normalshapemediumseriesnormalshapemediumseries\autolines) or forced line break (using
normalshapemediumseriesnormalshapemediumseries\alaligne or
normalshapemediumseriesnormalshapemediumseries\alapage). More precisely, it is executed
after the break and before the next system is typed. Thus it is fit for
posting new definitions of layout parameters, when no system is
pending2.21.
In some scores, tenor parts are not code using the
bass clef, but using rather the violin clef subscripted by a
normalshapemediumseries8. This is not directly supported by the
normalshapemediumseriesnormalshapemediumseries\cleftoksrnormalshapemediumseries=
command, but it can be handled using
normalshapemediumseriesnormalshapemediumseries\everystaff and
normalshapemediumseriesnormalshapemediumseries\zcharnote.
As an example the following score
was coded as:
\def\nbinstruments{4} \cleftoksi={6000} \cleftoksii={0000} \cleftoksiii={0000} \cleftoksiv={0000} \font\eightfig=cmr8 \def\everystaff{\znotes&\zcharnote{-6}{\eightfig \kern -1.4\Interligne 8}&\zcharnote{-6}{\eightfig \kern -1.4\Interligne 8}\enotes} \debutextrait \normal \NOtes\hu{HIJK}&\hu{efgh}&\hl{hijk}&\hl{hmlk}\enotes \finextraitwhere the
\eightfig
font declaration can obviously be omitted if
the TEX format declares an 8 point roman font.
