I am writing a musical exercise book with musixtex. I'm trying to typeset a single stave with some text positioned beneath it. There are no notes, only the key signatures change and I would like to annotate each bar with the key signature name.
These two examples demonstrate what I am trying to achieve:
\documentclass[11pt,a4paper,BCOR=12mm,DIV=24,headsepline=true,parskip=half]{scrbook}
\usepackage{musixtex}
\begin{document}
% First example, right layout but text missing
\begin{music}
\generalsignature{0}
\nostartrule
\nobarnumbers
\startpiece\addspace\afterruleskip
\generalsignature{+1}\ignorenats\Changecontext
\generalsignature{+2}\ignorenats\Changecontext
\generalsignature{+3}\ignorenats\Changecontext
\generalsignature{+4}\ignorenats\Changecontext
\generalsignature{+5}\ignorenats\Changecontext
\generalsignature{-1}\ignorenats\Changecontext
\generalsignature{-2}\ignorenats\Changecontext
\generalsignature{-3}\ignorenats\Changecontext
\generalsignature{-4}\ignorenats\Changecontext
\generalsignature{-5}\ignorenats\Changecontext
\setdoublebar
\endpiece
\end{music}
% Second example, adding text messes up layout
\begin{music}
\generalsignature{0}
\nostartrule
\nobarnumbers
\startpiece\addspace\afterruleskip
\lcharnote{P}{\smalltype{C-Dur}}
\generalsignature{+1}\ignorenats\Changecontext
\lcharnote{P}{\smalltype{G-Dur}}
\generalsignature{+2}\ignorenats\Changecontext
\lcharnote{P}{\smalltype{D-Dur}}
\generalsignature{+3}\ignorenats\Changecontext
\lcharnote{P}{\smalltype{A-Dur}}
\generalsignature{+4}\ignorenats\Changecontext
\lcharnote{P}{\smalltype{E-Dur}}
\generalsignature{+5}\ignorenats\Changecontext
\lcharnote{P}{\smalltype{H-Dur}}
\generalsignature{-1}\ignorenats\Changecontext
\lcharnote{P}{\smalltype{F-Dur}}
\generalsignature{-2}\ignorenats\Changecontext
\lcharnote{P}{\smalltype{B-Dur}}
\generalsignature{-3}\ignorenats\Changecontext
\lcharnote{P}{\smalltype{Es-Dur}}
\generalsignature{-4}\ignorenats\Changecontext
\lcharnote{P}{\smalltype{As-Dur}}
\generalsignature{-5}\ignorenats\Changecontext
\lcharnote{P}{\smalltype{Des-Dur}}
\setdoublebar
\endpiece
\end{music}
\end{document}
Please note that this example has to be compiled in a three step process:
$ pdflatex example.tex
$ musixflx example.tex
$ pdflatex example.tex

In the first example, the layout is correct, but the text is not included yet. In the second example, I tried to include the text, but this adds unwanted horizontal space and the layout is messed up, although the documentation promises in section 2.6.13 that no horizontal space will be added.
Also, it would be nice if the text would be centered within each bar.
Does anyone have an idea how to fix the example, or a different solution to achieve the same thing?
Thank you!

\lcharnote{P}{\smalltype{C-Dur}}. If you replace those lines by\lcharnote{P}{\smalltype{C-Dur}}%the spacing of both examples is the same – cgnieder Dec 29 '13 at 16:34
