77 BPM in Milliseconds: Delay Times and Note Lengths
At 77 BPM one beat (a quarter note) lasts 779.221 ms and one bar of 4/4 lasts 3.117 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.
77 BPM at a glance
- One beat at 77 BPM lasts about 779.22 ms (60,000 divided by 77), an eighth note about 389.61 ms and a dotted eighth about 584.42 ms.
- A beat here is not a whole number of milliseconds. The nearest tempo where it is: 75 BPM, with 800 ms per beat.
- A beat is 34,363.636 samples at 44.1 kHz and 37,402.597 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 12.468 seconds, and 3 minutes of music at this tempo holds 57.75 bars of 4/4.
- Going from 77 to 78 BPM shortens each beat by 9.99 ms, about 1.28% of the beat.
- An LFO synced to quarter notes runs at about 1.283 Hz; synced to whole bars of 4/4 it runs at about 0.3208 Hz.
