87 BPM in Milliseconds: Delay Times and Note Lengths
At 87 BPM one beat (a quarter note) lasts 689.655 ms and one bar of 4/4 lasts 2.759 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.
87 BPM at a glance
- One beat at 87 BPM lasts about 689.66 ms (60,000 divided by 87), an eighth note about 344.83 ms and a dotted eighth about 517.24 ms.
- A beat here is not a whole number of milliseconds. The nearest tempo where it is: 80 BPM, with 750 ms per beat.
- A beat is 30,413.793 samples at 44.1 kHz and 33,103.448 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 11.034 seconds, and 3 minutes of music at this tempo holds 65.25 bars of 4/4.
- Going from 87 to 88 BPM shortens each beat by 7.837 ms, about 1.14% of the beat.
- An LFO synced to quarter notes runs at 1.45 Hz; synced to whole bars of 4/4 it runs at 0.3625 Hz.
