This repository contains the unpacked and mildly commented source for the TIC-80 256b intro Requiem for a piggy, made by pestis / bC! and released at Flashparty 2021.
Note that the newline works as it should after packing; pactic embeds the
function in single quotes TIC=load'..."\\n"...'. But if you preview the .lua,
it won't work. Hopefully future versions of pactic handle string escape chars
properly.
The music is just rehashing p01's ideas for Music for tiny airports, which in turn was apparently inspired by Brian Eno. I just made the loops shorter and of lengths 1,2,3,4 (lowest common multiple 12), so it feels less ambient and more rythmic.
The only interesting discovery worth mentioning here is the fact that the note numbers (semitones) of a minor chord with an added octave are: 0-3-7-12. These can be generated with a quadratic function x*(x+5)/2.
Major triad with an added octave is 0-4-7-12, which is not a quadratic function. But the second inversion of a major triad is 0-5-9-12 and these are generated by a quadratic function x*(11-x)/2. This equation is close to the equation for a minor chord. So it was easy to devise an equation that generates either minor or major chords depending on the part of the song. All that remained was to shift the bass note to create chord progressions (taking into account the second inversion); these were just tabulated.
For the minor chords, 0-7-12-15 would have been a slightly more spaced out voicing and sounded better; this voicing is generated by an even shorter equation x*(8-x). But I didn't find similarly spaced out voicings for major triads. The change from minor to major triad equation seemed to consume more bytes with this equation, so I had to leave it out.
Oh, the backstory is some joke with ps on discord, don't ask.
Tested with TIC-80 0.90.1723, packed with pactic. Remember to add -c option.
