I beepbox-ified arma virumque, a tune I remember working out with groen years ago (probably at least about 7 years ago to be exact, given this mention of it from jun '07) who'd written the lyrics (which I no longer know where they got to) and maybe is to credit for most of the melody? I remember coming up with the chords, I think? Anyway good times nostalgia nostalgia mumbles.
Not totally sure how well it works as chiptunes, since I imagined it more as a very dignified classical-instrumented march or something. Still I like how the chorus came together, all note-dense and such.
even better version - more dynamic contrast between verse and chorus, smoothed out some of the melodic rhythm.
