{\centering\section*{Using the turn ornament {\PMX} }

The `turnï (`gruppettoï in Italian) is quite a commonly used ornament;
however, although available in MusiXTeX, it is (for technical/historical
reasons) not defined in {\PMX}.

\medskip
Of course, you can always resort to inline {\TeX}. But that may be a bit
too much of a task for many non-TeXperts, in particular considering how
simple the problem actually is.

Luckily, Don Simons has suggested a rather easy-to-use trick: simply
redefine a particular {\PMX} ornament that you use only rarely!

So how about \verb"os" ? \verb"os" (called ``\verb"\mtr"ïï by the {\PMX}
program itself) is sometimes used in renaissance music; it consists of 2
light slashes.

So if you want to follow that suggestion and redefine \verb"os", , simply add
\begin{center} \verb"\\let\mtr\turn\" \end{center
(on a line of its own) before the first use of \verb"os" , and from then
on \verb"os" will produce a turn wherever it appears in your {\PMX}
source.

\bigskip
You can, of course, redefine any {\PMX} ornament you like. Just remember
that the original ornament that you replaced will now no longer be
available (One of the advantages of using \verb"os" for that purpose is
that is undocumented; so that many  {\PMX} will not even have been aware of
the fact that they have replaced a  {\PMX} symbol.
