Change the groove
Keep the BPM. Change how the rhythm moves.
One ruler, four relationships
Compare A and B in each stage. The cycle, four main pulses and 120 BPM stay fixed.
01 / 04 · Accent
The weight changes. The pulse does not.
Events occupy exactly the same positions. Hear the weight move.
Only local dynamics change; positions, count, timbre and cycle remain.
The beats remain in the same places. The weight changed.
01 · Accent
The weight changes. The pulse does not.
Only local dynamics change; positions, count, timbre and cycle remain.
The beats remain in the same places. The weight changed.
02 · Syncopation
Expectation changes.
Only the featured event position changes; pulse, timbre, gain and cycle remain.
The pulse continues. The events’ relationship to it changed.
03 · Subdivision / swing
The space inside the pulses changes.
Only the inner subdivision position changes; main pulses stay fixed.
The pulses remain in the same places. The division of space between them changed.
04 · Timing
Small differences are not magic.
Only local offsets of about 18–23 ms change; they never accumulate.
Timing can vary without the pulse disappearing. Groove does not require events off the grid.
The code in one sentence
BPM marks the ruler. Groove decides how rhythm moves within it.
Accent distributes weight; syncopation changes expectation; subdivision and swing reorganize inner space; timing moves local positions.
- Accent: weight
- Syncopation: expectation
- Subdivision / swing: inner space
- Timing: local position
None of these elements alone determines a universal groove feeling. Context, style, familiarity and individual perception also take part.
In C05, listening moves from rhythmic motion to the elements that make up a track.
