155 BPM in Milliseconds: Delay Times and Note Lengths
At 155 BPM one beat (a quarter note) lasts 387.097 ms and one bar of 4/4 lasts 1.548 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.
155 BPM at a glance
- One beat at 155 BPM lasts about 387.1 ms (60,000 divided by 155), an eighth note about 193.55 ms and a dotted eighth about 290.32 ms.
- A beat here is not a whole number of milliseconds. The nearest tempo where it is: 150 BPM, with 400 ms per beat.
- A beat is 17,070.968 samples at 44.1 kHz and 18,580.645 samples at 48 kHz, neither a whole number, so sample accurate loop points round slightly at both rates.
- A 4 bar phrase in 4/4 takes about 6.194 seconds, and 3 minutes of music at this tempo holds 116.25 bars of 4/4.
- Going from 155 to 156 BPM shortens each beat by 2.481 ms, about 0.64% of the beat.
- An LFO synced to quarter notes runs at about 2.583 Hz; synced to whole bars of 4/4 it runs at about 0.6458 Hz.
