How do I calculate BPM?

Count the number of beats over a timed interval, then multiply by 60 and divide by seconds elapsed. For example, 32 beats in 15 seconds = (32/15) × 60 = 128 BPM.

What is Allegro tempo?

Allegro means "fast and lively" in Italian and corresponds to roughly 120–168 BPM. Other common markings include Andante (76–108 BPM, walking pace), Moderato (108–120 BPM), and Presto (168–200 BPM, very fast).

How do I convert BPM to milliseconds?

A quarter note in milliseconds = 60,000 ÷ BPM. At 120 BPM, a quarter note = 500 ms. An eighth note = 250 ms. This is essential for setting delay and reverb times in music production.

What BPM is used in electronic dance music?

House music typically runs 120–130 BPM, Techno 130–150 BPM, Drum and Bass 160–180 BPM, and Trap 130–160 BPM with half-time feels around 65–80 BPM.

Formula

BPM = (Beats ÷ Seconds) × 60

Quarter Note (ms) = 60,000 ÷ BPM

Dotted Eighth (ms) = Quarter Note × 0.75 — commonly used for slapback delay settings.

Example

You count 32 beats in 15 seconds: BPM = (32 ÷ 15) × 60 = 128 BPM (Allegro). At 128 BPM: Quarter note = 468.75 ms, Eighth note = 234.4 ms, Dotted eighth = 351.6 ms.
