The equation

y = x mod 7

What the equation decides

A 7-note banjo roll runs over a 16-step bar, so its bright top note walks across the beat, bar after bar. In the break the roll shrinks to 5 and the accents crowd together.

What was composed

Fiddle hook, chords, verse line, upright bass and stomp.
