+The soundfount ``font.h`` has been produced in this way:
+
+1. download
+   https://github.com/schellingb/TinySoundFont/blob/master/examples/florestan-subset.sf2
+2. use something like `Polyphone
+   <https://www.polyphone-soundfonts.com/>`_ to remove all presets,
+   instruments and samples apart from the "Piano"
+3. use ``perl soundfont2-to-c-header florestan-subset.sf2 font.h`` to
+   dump the reduced font to a C header file
+
+The TinySoundFont library is under the MIT license, but the font is
+very probably from `Nando Florestan
+<http://dev.nando.audio/pages/soundfonts.html>`_; the license for it
+is unclear to me.
