Each genre has characteristic groove parameters: drag/rush amounts, swing ranges, and which elements vary

Groove choices are genre-specific and historically determined. Hip-hop: dragged snares (10–20ms back), quintuplet/septuplet subdivisions for Dilla style, kicks tighter than snares. Trap: tight to grid, groove via hi-hat roll variations that rush forward. House: kicks close to grid, occasional early closed hats, sidechain pumping is the primary groove source. Techno: near-grid with subtle percussion timing shifts; groove via filter modulation. Drum & bass: huge sub-genre variation — liquid DnB is looser; neurofunk rushes hi-hats 5–8ms forward. Neo-soul: heavy drag on snares, loose quintuplet feel, everything behind the beat. Reggae/dub: heavy drag on everything, especially kick. Afrobeat: straight foundation, rushed auxiliary percussion — the contrast between tight and loose creates polyrhythmic tension. These profiles are learnable heuristics, not rigid rules, but they give starting points that can then be exaggerated or inverted for character.

Examples

Building a neo-soul beat: drag the snare 15ms, drag kicks 8ms, apply 60% swing, randomize hi-hat velocity 15%. Building a trap beat: keep kick/snare tight to grid, rush hi-hat rolls slightly forward, use 55% swing only on hats.

Assessment

Given a beat labeled ‘hip-hop’ and a beat labeled ‘trap,’ predict the expected timing strategy for each (rushing vs dragging, where applied, approximate amounts). Then explain why house music achieves groove through sidechain rather than micro-timing.
