Gavin Harrison
Porcupine Tree · Rhythmic illusion and groove displacement
The grooves Gavin Harrison actually uses across their path, moves and song studies — each one opens the same exercise workout the rest of the app links to.
Kick Placement Drill
Level 2Groove · 55–140 BPM
Your hands play the exact same thing every bar. Only the kick moves. This builds the 'my foot goes where I want' skill that everything else depends on.
Goal: Tight, creative kick phrasing under a static groove
WorkoutSnare Displacement
Level 3Groove · 55–130 BPM
Normally the snare lands on 2 and 4. Here you slide it slightly later each time — onto the 'e', then the '&', then the 'a' — while the hi-hat and kick refuse to move.
Goal: You feel the pulse independently of the backbeat
WorkoutLinear Groove Around the Kit
Level 3Groove · 55–130 BPM
'Linear' means only one limb sounds at a time — no kick and hi-hat together, ever. It forces your hands off the snare and onto the toms to fill the space.
Goal: Modern linear groove vocabulary you can drop into a fill
