174 BPM

How long is a beat at 174 BPM?

At 174 BPM a quarter note lasts 344.83 ms (60,000 ÷ 174). An eighth is 172.41 ms, a dotted eighth 258.62 ms, a sixteenth 86.21 ms and a sixteenth triplet 57.47 ms. A one-beat LFO runs at 2.9 Hz, and one 4/4 bar lasts 1,379.31 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 drum and bass track at 174 BPM with a reese bass LFO on the filter

1Quarter note: 60,000 ÷ 174 = 344.83 ms
2Eighth note: 344.83 ÷ 2 = 172.41 ms; dotted: 172.41 × 1.5 = 258.62 ms
3Sixteenth triplet: 86.21 × 2/3 = 57.47 ms
4LFO once per beat: 1000 ÷ 344.83 = 2.9 Hz
5Hall reverb: pre-delay 1/64 = 21.55 ms, decay 2,737.07 ms to end on 2 bars

At 174 BPM: 344.83 ms quarter, 258.62 ms dotted eighth, 57.47 ms sixteenth triplet, 2.9 Hz per beat.

Frequently asked questions

What is the dotted eighth delay time at 174 BPM?

258.62 ms. An eighth note at 174 BPM is 172.41 ms, and a dot adds half again: 172.41 × 1.5 = 258.62 ms. The dotted quarter is twice that, 517.24 ms, and the plain quarter 344.83 ms.

What music is made at 174 BPM?

Mostly drum and bass and neurofunk. 174 BPM is the standard modern drum and bass tempo. Its quarter note, 344.83 ms, is a repeating decimal, so tempo-synced plugins hold time better than hand-set hardware; if you set a pedal to 345 ms, retrigger it each phrase. Reese bass filter LFOs often run at 1/4 or 1/2 notes, 2.9 or 1.45 Hz.

What is 174 BPM in half time and double time?

Half time is 87 BPM, with a 689.66 ms quarter note; double time is 348 BPM, with a 172.41 ms quarter note. A delay set to a quarter note at 174 BPM is a half note in double time and an eighth note in half time, so it stays in sync either way.
