70 BPM

How long is a beat at 70 BPM?

At 70 BPM a quarter note lasts 857.14 ms (60,000 ÷ 70). An eighth is 428.57 ms, a dotted eighth 642.86 ms, a sixteenth 214.29 ms and a sixteenth triplet 142.86 ms. A one-beat LFO runs at 1.17 Hz, and one 4/4 bar lasts 3,428.57 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

This page uses the same method as the BPM to MS Calculator, which explains each term and assumption in full.

Worked example

A dub mix at 70 BPM with tape-style echoes on the snare

1Quarter note: 60,000 ÷ 70 = 857.14 ms
2Eighth note: 857.14 ÷ 2 = 428.57 ms; dotted: 428.57 × 1.5 = 642.86 ms
3Sixteenth triplet: 214.29 × 2/3 = 142.86 ms
4LFO once per beat: 1000 ÷ 857.14 = 1.17 Hz
5Hall reverb: pre-delay 1/64 = 53.57 ms, decay 6,803.57 ms to end on 2 bars

At 70 BPM: 857.14 ms quarter, 642.86 ms dotted eighth, 142.86 ms sixteenth triplet, 1.17 Hz per beat.

Frequently asked questions

What is the dotted eighth delay time at 70 BPM?

642.86 ms. An eighth note at 70 BPM is 428.57 ms, and a dot adds half again: 428.57 × 1.5 = 642.86 ms. The dotted quarter is twice that, 1,285.71 ms, and the plain quarter 857.14 ms.

What music is made at 70 BPM?

Mostly dub, downtempo, slow R&B and half-time trap. 70 BPM is the home of dub and slow R&B, and the half-time feel of 140 BPM trap and dubstep, so the same delay times work for both. Dub engineers traditionally ride the delay feedback by hand, and a dotted eighth or quarter-note echo on the snare is the signature sound.

What is 70 BPM in half time and double time?

Half time is 35 BPM, with a 1,714.29 ms quarter note; double time is 140 BPM, with a 428.57 ms quarter note. A delay set to a quarter note at 70 BPM is a half note in double time and an eighth note in half time, so it stays in sync either way.
