80 BPM

How long is a beat at 80 BPM?

At 80 BPM a quarter note lasts 750 ms (60,000 ÷ 80). An eighth is 375 ms, a dotted eighth 562.5 ms, a sixteenth 187.5 ms and a sixteenth triplet 125 ms. A one-beat LFO runs at 1.33 Hz, and one 4/4 bar lasts 3,000 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 lo-fi hip-hop beat at 80 BPM with a tape echo on the keys

  1. 1Quarter note: 60,000 ÷ 80 = 750 ms
  2. 2Eighth note: 750 ÷ 2 = 375 ms; dotted: 375 × 1.5 = 562.5 ms
  3. 3Sixteenth triplet: 187.5 × 2/3 = 125 ms
  4. 4LFO once per beat: 1000 ÷ 750 = 1.33 Hz
  5. 5Hall reverb: pre-delay 1/64 = 46.88 ms, decay 5,953.13 ms to end on 2 bars

At 80 BPM: 750 ms quarter, 562.5 ms dotted eighth, 125 ms sixteenth triplet, 1.33 Hz per beat.

Frequently asked questions

What is the dotted eighth delay time at 80 BPM?

562.5 ms. An eighth note at 80 BPM is 375 ms, and a dot adds half again: 375 × 1.5 = 562.5 ms. The dotted quarter is twice that, 1,125 ms, and the plain quarter 750 ms.

What music is made at 80 BPM?

Mostly lo-fi hip-hop, soul and slow rock. 80 BPM is a common lo-fi hip-hop and soul tempo. Its beat is 750 ms, long enough that a quarter-note delay reads as a distinct echo, so many producers use eighths or dotted eighths on keys and guitar instead and keep quarters for throws.

What is 80 BPM in half time and double time?

Half time is 40 BPM, with a 1,500 ms quarter note; double time is 160 BPM, with a 375 ms quarter note. A delay set to a quarter note at 80 BPM is a half note in double time and an eighth note in half time, so it stays in sync either way.
