Flam

Practice tempo
What it teaches
The base flam technique itself — striking with both hands at different heights so one hand's grace note lands a fraction of a second before the other hand's full-volume primary stroke, fusing into what should sound like one slightly longer, thicker note rather than two separate hits.
The common mistake
Both hands strike from the same height, producing a flat double-stop (two simultaneous, evenly loud notes) instead of a flam; the correction is deliberately setting the grace-note hand low, just above the head, while the primary-stroke hand stays at a normal playing height, so the height difference — not just timing — creates the separation.
Tempo progression
Start at 66 BPM alternating one flam per hand, listening for a single thickened note rather than two distinct hits. Add 8 BPM once ten flams in a row sound fused rather than split; most players keep a clean flam through 140-160 BPM before the grace note starts blending in too far to hear at all.
Where it shows up
The foundational technique every other rudiment in this batch is built from — used constantly on its own as an accent thickener in drum-set grooves and fills, not just as a building block for the more complex flam rudiments.
