Drum and bass BPM

How fast, and who says so

Where the two sources overlap: 160–180 BPM. Each in its own words:

• Wikipedia, Drum and bass: 160–180 BPM
• Soundtrap, How To Find BPM Of A Song (2025): 160–180 BPM

The groove on this page

Drum and bass gets its speed from a sparse pattern: a kick on the one and on the and of three, snares on two and four, the two-step that came out of chopped breakbeats. At 174 the snares fall 690 ms apart, so a crowd moves at half the tempo while the hats and ghost notes run at full speed. Wikipedia notes most of it has stayed between 170 and 180 since the late nineties; iZotope's guide simply names 174.

On this page: the app's Bright kit at 174 BPM, straight 16ths, with the Sub bass sound.

Delay and LFO values

A delay in time with the track repeats once per note value: a quarter note lasts 60,000 divided by the BPM, in milliseconds. Dotted is one and a half times that, triplet two thirds. An LFO synced to a note value cycles at 1,000 divided by those milliseconds, in Hz. The table follows the tempo above: − and + move it, and so does a tempo you tap.

Genres near this tempo

• Psytrance: 138–148 BPM

• Trap: 130–176 BPM

Then make something of it

The door opens Brumm, a club track with a beat and a bass, with this groove's low end in it. The app runs between 90 and 150 BPM, so a faster or slower tempo goes in at half or double. No account, no upload: it travels inside the link. Hum a line over it, and it becomes an instrument.

Nothing is recorded: no microphone, only your taps, counted in the browser. The groove's sounds are the app's own samples, fetched when you tap Play. How the site counts visits.
