Halftime / Doubletime

Enter a BPM to see half speed and double speed variants at a glance. Useful for planning transitions between genres with different energy levels — like mixing a 140 BPM dubstep track (halftime BPM of 70) into a 128 BPM house track.

When to Use This

Planning transitions between genres with different BPM ranges
Dubstep (140 BPM) has a halftime feel of 70 BPM — matching it with a downtempo track
Drum & bass (174 BPM) at halftime sits near house tempo (87 BPM)
Finding triplet grooves for polyrhythmic mixing

What Is Halftime and Doubletime?

Halftime and doubletime BPM are tempo relationships that let DJs bridge genres with vastly different BPM ranges. Playing a track at half speed — for example, a dubstep track at 140 BPM — gives you the same pulse as a 70 BPM track; the kick drums align perfectly when beatmatched. Similarly, drum and bass at 174 BPM at half speed sits near house at 87 BPM. Understanding these halftime and doubletime relationships opens up creative transition possibilities between genres that seem incompatible at first glance.

Frequently Asked Questions

Halftime BPM is exactly half the original tempo. A track at 140 BPM has a halftime feel of 70 BPM. Many genres like dubstep use halftime rhythms — the drums play at half speed while the actual BPM remains high, creating a heavy, spacious feel.

Doubletime is simply the original BPM multiplied by 2. A 87 BPM hip-hop beat at doubletime is 174 BPM — which is drum and bass territory. This mathematical relationship is why DJs can transition between seemingly different genres.

Dubstep runs at 140 BPM, so its halftime feel is 70 BPM. The kick and snare pattern hits on the halftime grid even though the track itself plays at 140 — this is why dubstep feels heavy and slow despite the high tempo. For the full dubstep tempo breakdown, see our dubstep BPM guide.

Most hip-hop sits at 80–95 BPM. At doubletime, 85 BPM becomes 170 BPM and 87 BPM becomes 174 BPM — both squarely inside drum and bass territory. This 2:1 relationship is why DJs can transition between hip-hop sets and D&B sets without a jarring tempo shift.

Not exactly. Drumstep is a sub-genre of drum and bass that uses a halftime kick-snare pattern over a 174 BPM foundation — so the track technically runs at D&B tempo but feels like 87 BPM. Halftime, in general, is the rhythmic concept; drumstep is one specific genre that applies it.

Triplet tempos let you bridge genres that don't align on a 2:1 ratio. Multiplying a BPM by 2/3 (triplet down) or 3/2 (triplet up) creates polyrhythmic relationships — useful for going from 120 BPM house into 180 BPM drum and bass via an 80 BPM bridge track.
