73 BPM in Milliseconds: Delay Times and Note Lengths
At 73 BPM one beat (a quarter note) lasts 821.918 ms and one bar of 4/4 lasts 3.288 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.
73 BPM at a glance
- One beat at 73 BPM lasts about 821.92 ms (60,000 divided by 73), an eighth note about 410.96 ms and a dotted eighth about 616.44 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 36,246.575 samples at 44.1 kHz and 39,452.055 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 13.151 seconds, and 3 minutes of music at this tempo holds 54.75 bars of 4/4.
- Going from 73 to 74 BPM shortens each beat by 11.107 ms, about 1.35% of the beat.
- An LFO synced to quarter notes runs at about 1.217 Hz; synced to whole bars of 4/4 it runs at about 0.3042 Hz.
