Lorsqu'il est impossible d'obtenir facilement une allure particulière
pour les têtes de note en recourant à la technique du @code{\\markup}, un
code PostScript peut vous tirer d'embarras.  Voici comment générer des
têtes ressemblant à des parallélogrammes.

When a note head with a special shape cannot easily be generated with
graphic markup, PostScript code can be used to generate the shape.
This example shows how a parallelogram-shaped note head is generated.
