This extension adds an abc directive to Sphinx in order to write sheet music as text. The content of the directive will be rendered to SVG by abcm2ps and included in the rendered document.

Here are some inversions of a D-major triad.

.. abc::

    X:1
    L:1/4
    K:C
    "Root position"[D^FA] [DA^f] | "First inversion"[^FAd] [^Fda] | "Second inversion"[Ad^f] [Ad'^f] |
    w: closed open closed open closed open
