How long is a beat at 100 BPM?

At 100 BPM a quarter note lasts 600 ms (60,000 ÷ 100). An eighth is 300 ms, a dotted eighth 450 ms, a sixteenth 150 ms and a sixteenth triplet 100 ms. A one-beat LFO runs at 1.67 Hz, and one 4/4 bar lasts 2,400 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 pop record at 100 BPM with a stereo eighth-note delay on the guitar

  1. 1Quarter note: 60,000 ÷ 100 = 600 ms
  2. 2Eighth note: 600 ÷ 2 = 300 ms; dotted: 300 × 1.5 = 450 ms
  3. 3Sixteenth triplet: 150 × 2/3 = 100 ms
  4. 4LFO once per beat: 1000 ÷ 600 = 1.67 Hz
  5. 5Hall reverb: pre-delay 1/64 = 37.5 ms, decay 4,762.5 ms to end on 2 bars

At 100 BPM: 600 ms quarter, 450 ms dotted eighth, 100 ms sixteenth triplet, 1.67 Hz per beat.

Frequently asked questions

What is the dotted eighth delay time at 100 BPM?

450 ms. An eighth note at 100 BPM is 300 ms, and a dot adds half again: 300 × 1.5 = 450 ms. The dotted quarter is twice that, 900 ms, and the plain quarter 600 ms.

What music is made at 100 BPM?

Mostly reggaeton-adjacent pop, funk and pop ballads. 100 BPM gives the roundest numbers after 60 and 120: a 600 ms quarter, 300 ms eighth and 450 ms dotted eighth, which are easy to dial into any hardware. It is common in pop, funk and reggaeton-influenced records, the latter often sitting just below at 90 to 98.

What is 100 BPM in half time and double time?

Half time is 50 BPM, with a 1,200 ms quarter note; double time is 200 BPM, with a 300 ms quarter note. A delay set to a quarter note at 100 BPM is a half note in double time and an eighth note in half time, so it stays in sync either way.
