PostScript lines

You can add solid, dashed, and dotted lines using embedded Postscript.

For technical reasons, this doesn't show up in the Wiki because \postscript only works with LilyPond's PS backend and is neither supported in the SVG (used in this Wiki) nor in the Cairo backend.

In general it is recommended to use LilyPond's native graphical markup commands like \path instead, which can be used with all LilyPond backends; see snippets Brackets indicating “Hauptstimme” and “Nebenstimme” and Curly end barline for examples.
