Hm, maybe being extraordinarily busy will force me to finally do some things that are actually accessible to people. Here's another easy thing, illustrating half time feel and double time feel using basic rock beats. Playing a double time or half time feel in this case means halving or doubling the feel rhythmically within the original tempo-- instead of playing the snare drum backbeats on beats 2 and 4, you play them on beat 3, or on the &s of every beat. A true double time or half time involves an actual change in tempo, and would be written the same as the original beat-- the first two measures of each line-- with a written notation telling you to play half (or twice) as fast.
Play each section with repeats and without, then play the entire page without stopping.
