64 BPM

64 beats per minute is one beat every 937.5 ms. Below: bar and phrase lengths, delay and reverb times, LFO rates, the genres that use this tempo, and the pitch change needed to mix in from nearby tempos. Start the metronome or tap along to a track to check it is really 64.

Beat, bar and phrase lengths at 64 BPM

At 64 BPM one beat lasts 937.5 ms and a 4/4 bar lasts 3.75 s. The beat is not a whole number of milliseconds, so round to the nearest 0.1 ms when you type times in by hand, or use your plugin's tempo sync. That is 1.067 beats per second, or 16 bars of 4/4 per minute.

Dance tracks are usually arranged in 8-, 16- and 32-bar phrases. At 64 BPM a 16-bar phrase takes 1:00.0 min and a 32-bar intro or outro takes 2:00.0 min. That is 28 s longer than the same 16 bars at 120 BPM. A six-minute track at this tempo contains about 96 bars.

Delay times at 64 BPM

Straight values follow the beat; dotted values are 1.5 times as long and triplets are two-thirds as long. At 64 BPM the popular dotted-eighth delay is 703.13 ms and a quarter-note slapback is 937.5 ms. The Hz column is the matching rate for an LFO, tremolo or auto-pan synced to the straight note.

Reverb times at 64 BPM

A common way to keep a reverb in time is to tie its pre-delay to a short note value and let the tail fade within a longer one. At 64 BPM a 1/64-note pre-delay is 58.59 ms and a 1/32-note pre-delay is 117.19 ms.

The decay control on most reverbs is RT60, the time it takes the tail to fall by 60 dB, so the audible tail ends earlier than the number shown. Treat these values as starting points and adjust by ear.

Genres at 64 BPM

64 BPM is a slow tempo; many listeners will also hear it at double-time. It sits near the low end of the ambient/downtempo range (60–100).

Counted at double-time (128 BPM) it matches pop, disco, house, UK garage/breakbeat, techno and trance. A detector or a tag in your library may report either reading, so check by ear which one the drums suggest.

These ranges are common practice rather than rules: genre is decided by rhythm, sound and scene as much as by tempo, and plenty of tracks sit outside the usual numbers.

  • Ambient/downtempo: typically 60–100 BPM — beatless ambient may not have a useful BPM at all.

Mixing into 64 BPM

To bring a track at another tempo up or down to 64 BPM, move its pitch fader by the percentage below. Without key lock the key moves too, by the number of semitones shown; about 6 % is one semitone, so changes beyond that are where key lock (master tempo) starts to matter.

A ±8 % pitch fader on a track at 64 BPM reaches 58.9–69.1 BPM; a ±16 % range reaches 53.8–74.2 BPM.

Half-time, double-time and nearby tempos

Half-time of 64 BPM is 32 BPM and double-time is 128 BPM.

32 BPM is outside the 60–200 range of these pages; the half/double-time converter works with any value.

Each 1 BPM step at this tempo changes the beat by about 14.42 ms, so neighbouring tempos are close enough to beatmatch with a small pitch move.

Frequently asked questions

How many milliseconds is one beat at 64 BPM?
One beat (a quarter note) at 64 BPM is 60,000 ÷ 64 = 937.5 ms. A 4/4 bar is four beats, 3750 ms.
What is the dotted eighth delay time at 64 BPM?
A dotted 1/8 delay at 64 BPM is 703.13 ms: an eighth note (468.75 ms) multiplied by 1.5. A straight quarter-note delay is 937.5 ms and a quarter-note triplet is 625 ms.
What genre is 64 BPM?
Ambient/downtempo commonly uses 64 BPM. Genre ranges overlap, so the drum pattern and sound decide the style more than the number does.
What is 64 BPM in Hz?
64 BPM is 1.0667 Hz when one cycle equals one beat. An LFO synced to one bar runs at 0.2667 Hz, and one synced to sixteenth notes at 4.267 Hz.
