Sorry, but I can't refrain from making the following proposal: :-)

\documentclass{article}
\usepackage{musixtex}
\input musixlyr
\font\ChordSymbolSmall=musix13
\def\flt{\raise 1.7pt\hbox{\ChordSymbolSmall\char50}}
\begin{document}
\begin{music}
\setlyrics1{\lyrlayout\smalltype 1 2 \flt3 4 5 \flt6 \flt7}
\assignlyrics11
\startextract
\Notes\nq{cd_efg'_ab}\lpar c\rpar c\nolyr\nq c\en
\endextract
\end{music}
\end{document}

But if you insist on doing the job without musixlyr: I don't quite
understand whether you intend to give the text line explicitly, like:
\doit{cd_efg'_ab}{12{\flt3}45{\flt6}{\flt7}}
.. or whether the scale digits shall be deduced automatically from the
notes sequence. Depending on this decision, the difficulty of
finding a solution may vary very much.

Re: [TeX-music] TeX programming
The second scale does get the numers (the lyrics) gathered to the right of the music extract. What am I doing wrong? Page 19. \resetlyrics. RTFM! Sorry for wasting bandwith.:-) Stefan ___ TeX-music mailing list [EMAIL PROTECTED] http://sunsite.dk/mailman/listinfo/tex-music

This looks like beeing a job for \futurelet: \futurelet\a\b... sets \a
to the first token of ... and executes then \b. You may set up a loop
using this control sequence by iteration:
1 append an end character to the string
2 read the first character into a macro
3 if it is not the end character
- process it
- set a temporary macro to the operations 2-4
else
- drop the end character
- set the temporary macro to a void action
4 put the temporary macro
this should look like follows (not tested)
\def\processtoken#1{whatever you want to do with the single tokens}
\def\setend#1{#1-}% sets an endmark (`-`) behind the string
\def\check{% checks one token
\if\temp-\let\next\relax
\else\processtoken\temp\let\next\iterate
\fi
\next
}
\def\iterate{\futurelet\temp\check}
\def\processstring#1{\expandafter\iterate\setend{#1}}
happy hacking
