Why is drum and bass 174 BPM?
Drum and bass standardised at 174 BPM in the late 1990s as the genre matured from jungle (160-170 BPM). 174 BPM offered enough speed for dancefloor energy while remaining playable on amen breaks and producible on early hardware samplers. The figure stuck and remains the genre's anchor today.
The 174 BPM standard
Drum and bass is anchored at 174 BPM as the de facto industry standard. While the genre operates between 160 and 180 BPM, the vast majority of modern DnB releases land at exactly 174 BPM.
Why exactly 174?
- Evolution from jungle. Jungle (the predecessor to DnB) ran 160-170 BPM in the early 1990s. As the genre split into liquid, neurofunk, and other subgenres in the late 1990s, the average tempo crept upward. 174 BPM emerged as the sweet spot — fast enough to feel like DnB, not so fast that it became hardcore.
- The amen break. Most DnB is built around chopped versions of the "Amen, Brother" drum break by The Winstons (1969). The amen break works rhythmically at 174 BPM — fast enough to drive, slow enough to retain the groove's detail.
- Hardware sampler limits. Early Akai S950 and S1000 samplers had tight memory. Producers worked at higher BPMs to fit more rhythmic content into shorter sample slots.
- Mixing convention. Once 174 became common, DJs preferred new tracks at the same BPM for clean mixing without large pitch adjustments.
Subgenre tempos within DnB
| Subgenre | BPM |
|---|---|
| Liquid DnB | 170-175 |

How DnB compares to other genres
174 BPM puts DnB on the boundary of Vivace (156-176 BPM) and Presto (176-200 BPM) on the Italian tempo scale. It's about 50 BPM faster than house and 30 BPM faster than dubstep (when dubstep is felt at full speed).
