150 BPM in Milliseconds: Delay Times and Note Lengths
At 150 BPM one beat (a quarter note) lasts 400 ms and one bar of 4/4 lasts 1.6 seconds. Below are the delay times for every note value, the same notes in Hz, bar and phrase lengths, samples per beat and the genres that typically sit at this tempo.
150 BPM at a glance
- One beat at 150 BPM lasts 400 ms (60,000 divided by 150), an eighth note 200 ms and a dotted eighth 300 ms.
- 150 BPM is one of the few tempos between 60 and 200 where a beat is a whole number of milliseconds, so quarter note delays need no rounding.
- At both 44.1 kHz and 48 kHz a beat is a whole number of samples (17,640 and 19,200), so loops cut on the beat line up exactly at either rate.
- A 4 bar phrase in 4/4 takes 6.4 seconds, and 3 minutes of music at this tempo holds 112.5 bars of 4/4.
- Going from 150 to 151 BPM shortens each beat by 2.649 ms, about 0.66% of the beat.
- An LFO synced to quarter notes runs at 2.5 Hz; synced to whole bars of 4/4 it runs at 0.625 Hz.

What music is 150 BPM?
Fast (140 to 159 BPM). This is a fast tempo. Some styles in this range are felt at half time, with the snare on beat 3 instead of 2 and 4, which makes a fast grid feel heavy and slow.
Typical tempo ranges that include 150 BPM: Techno, Trap (often felt at half time), Dubstep (felt at half time), Hardstyle, Punk.
Half time: 75 BPM, in the typical range of Ballads, Reggae, R&B, Downtempo and trip hop, Lofi hip hop. Double time: 300 BPM, faster than the genre ranges listed here.
A track can be written at one tempo and felt at the other, so a song at 150 BPM may be counted as 75 or 300 in a DAW or DJ software. Ranges are typical only; plenty of songs sit outside them.
