109 BPM in Milliseconds: Delay Times and Note Lengths
At 109 BPM one beat (a quarter note) lasts 550.459 ms and one bar of 4/4 lasts 2.202 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.
109 BPM at a glance
- One beat at 109 BPM lasts about 550.46 ms (60,000 divided by 109), an eighth note about 275.23 ms and a dotted eighth about 412.84 ms.
- A beat here is not a whole number of milliseconds. The nearest tempo where it is: 100 BPM, with 600 ms per beat.
- A beat is 24,275.229 samples at 44.1 kHz and 26,422.018 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 8.807 seconds, and 3 minutes of music at this tempo holds 81.75 bars of 4/4.
- Going from 109 to 110 BPM shortens each beat by 5.004 ms, about 0.91% of the beat.
- An LFO synced to quarter notes runs at about 1.817 Hz; synced to whole bars of 4/4 it runs at about 0.4542 Hz.
