Rattling Bog. In Lilypond.

So, there is this cummulative song: The rattling bog (performance e.g. here). I was recently helping someone with Lilypond, which I know can be scripted using Scheme (or Guile). So, naturally, it is a nice exercise in Scheme to implement this song in Lilypond itself, isn't it…

I do not know much about Scheme yet, so let me fix it :-)

Disclaimer: It is probably much better idea to generate the Lilypond source from another language and just use Lilypond to compile. But that is not as much fun :-)

The aim is to have as good as possible result (both PDF and MIDI), and hopefully reasonable code.

Possible features

• Melody for chorus and common stuff
• Correct number of syllables for the items
• Correct prepositions (in a hole vs. on a branch)
• Reasonable MIDI output
• Speeding up in later verses
