140 BPM

How long is a beat at 140 BPM?

At 140 BPM a quarter note lasts 428.57 ms (60,000 ÷ 140). An eighth is 214.29 ms, a dotted eighth 321.43 ms, a sixteenth 107.14 ms and a sixteenth triplet 71.43 ms. A one-beat LFO runs at 2.33 Hz, and one 4/4 bar lasts 1,714.29 ms.

quarter note (ms) = 60 000 ÷ BPM;  note = quarter × q;
dotted = note × 1.5;  triplet = note × 2/3;  rate (Hz) = 1000 ÷ ms;
bar = quarter × beats × 4 ÷ unit;  samples = seconds × sample rate

Worked example

A dubstep track at 140 BPM, written in half time against a 70 BPM feel

1Quarter note: 60,000 ÷ 140 = 428.57 ms
2Eighth note: 428.57 ÷ 2 = 214.29 ms; dotted: 214.29 × 1.5 = 321.43 ms
3Sixteenth triplet: 107.14 × 2/3 = 71.43 ms
4LFO once per beat: 1000 ÷ 428.57 = 2.33 Hz
5Hall reverb: pre-delay 1/64 = 26.79 ms, decay 3,401.79 ms to end on 2 bars

At 140 BPM: 428.57 ms quarter, 321.43 ms dotted eighth, 71.43 ms sixteenth triplet, 2.33 Hz per beat.

Frequently asked questions

What is the dotted eighth delay time at 140 BPM?

321.43 ms. An eighth note at 140 BPM is 214.29 ms, and a dot adds half again: 214.29 × 1.5 = 321.43 ms. The dotted quarter is twice that, 642.86 ms, and the plain quarter 428.57 ms.

What music is made at 140 BPM?

Mostly dubstep, grime, trap and UK garage. 140 BPM covers dubstep, grime and much trap, usually written in half time so the snare lands on beat 3. Delay times at 140 are exactly half those at 70, so you can set a pedal to either and stay in sync; wobble bass LFOs typically run at 1/8 or 1/16 notes, 4.67 or 9.33 Hz.

What is 140 BPM in half time and double time?

Half time is 70 BPM, with a 857.14 ms quarter note; double time is 280 BPM, with a 214.29 ms quarter note. A delay set to a quarter note at 140 BPM is a half note in double time and an eighth note in half time, so it stays in sync either way.
