A drum beat fills my mind. It never waivers, solid like a metronome. It's rhymically technical; like a mathematical equation with many variables, many integers. Some aspects of the rhythm never change, they are there, they are the backbone of the groove. Some of the aspects twirl this way and that, adding tripplets, adding rests, dotted eighths, dotted eighths with synchopated rests... They are the flavour of the groove.

Suddenly the rhythm changes, the backbone shifts; the solid ground on which the groove is founded alters. One single shot is missing. The sound is changed entirely. The end product is completely different. One integer changes the outcome.

One tiny aspect changes the entire effect.

One tiny rudder steers the ship.
