170 BPM

How long is a beat at 170 BPM?

At 170 BPM a quarter note lasts 352.94 ms (60,000 ÷ 170). An eighth is 176.47 ms, a dotted eighth 264.71 ms, a sixteenth 88.24 ms and a sixteenth triplet 58.82 ms. A one-beat LFO runs at 2.83 Hz, and one 4/4 bar lasts 1,411.76 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 liquid drum and bass track at 170 BPM with a long reverb on the pads

1Quarter note: 60,000 ÷ 170 = 352.94 ms
2Eighth note: 352.94 ÷ 2 = 176.47 ms; dotted: 176.47 × 1.5 = 264.71 ms
3Sixteenth triplet: 88.24 × 2/3 = 58.82 ms
4LFO once per beat: 1000 ÷ 352.94 = 2.83 Hz
5Hall reverb: pre-delay 1/64 = 22.06 ms, decay 2,801.47 ms to end on 2 bars

At 170 BPM: 352.94 ms quarter, 264.71 ms dotted eighth, 58.82 ms sixteenth triplet, 2.83 Hz per beat.

Frequently asked questions

What is the dotted eighth delay time at 170 BPM?

264.71 ms. An eighth note at 170 BPM is 176.47 ms, and a dot adds half again: 176.47 × 1.5 = 264.71 ms. The dotted quarter is twice that, 529.41 ms, and the plain quarter 352.94 ms.

What music is made at 170 BPM?

Mostly drum and bass, liquid and jungle. 170 BPM is the traditional drum and bass and liquid tempo, before much of the scene settled on 174. Drum and bass is felt both at full and half time (85 BPM), so delays are set from either; a dotted eighth at 170 is 264.71 ms.

What is 170 BPM in half time and double time?

Half time is 85 BPM, with a 705.88 ms quarter note; double time is 340 BPM, with a 176.47 ms quarter note. A delay set to a quarter note at 170 BPM is a half note in double time and an eighth note in half time, so it stays in sync either way.
