Beat, bar and phrase lengths at 133 BPM
At 133 BPM one beat lasts 451.13 ms and a 4/4 bar lasts 1.805 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 2.217 beats per second, or 33.25 bars of 4/4 per minute.
Dance tracks are usually arranged in 8-, 16- and 32-bar phrases. At 133 BPM a 16-bar phrase takes 28.87 s and a 32-bar intro or outro takes 57.74 s. That is 3.13 s shorter than the same 16 bars at 120 BPM. A six-minute track at this tempo contains about 200 bars.
| Length | Time | Milliseconds |
|---|---|---|
| 1 beat | 0.451 s | 451.13 ms |
| 1 bar (4 beats) | 1.805 s | 1804.51 ms |
| 4 bars | 7.218 s | 7218.05 ms |
| 8 bars | 14.44 s | 14436.09 ms |
| 16 bars | 28.87 s | 28872.18 ms |
| 32 bars | 57.74 s | 57744.36 ms |
| 64 bars | 1:55.5 min | 115488.72 ms |
Delay times at 133 BPM
Straight values follow the beat; dotted values are 1.5 times as long and triplets are two-thirds as long. At 133 BPM the popular dotted-eighth delay is 338.35 ms and a quarter-note slapback is 451.13 ms. The Hz column is the matching rate for an LFO, tremolo or auto-pan synced to the straight note.
| Note | Straight | Dotted | Triplet | Rate (straight) |
|---|---|---|---|---|
| 1/1 (one 4/4 bar) | 1804.51 ms | 2706.77 ms | 1203.01 ms | 0.554 Hz |
| 1/2 | 902.26 ms | 1353.38 ms | 601.5 ms | 1.108 Hz |
| 1/4 (one beat) | 451.13 ms | 676.69 ms | 300.75 ms | 2.217 Hz |
| 1/8 | 225.56 ms | 338.35 ms | 150.38 ms | 4.433 Hz |
| 1/16 | 112.78 ms | 169.17 ms | 75.19 ms | 8.867 Hz |
| 1/32 | 56.39 ms | 84.59 ms | 37.59 ms | 17.733 Hz |
Reverb times at 133 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 133 BPM a 1/64-note pre-delay is 28.2 ms and a 1/32-note pre-delay is 56.39 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.
| Reverb character | Pre-delay | Decay (RT60) |
|---|---|---|
| Tight room on drums | 28.2 ms | 451.13 ms |
| Medium plate on vocals | 56.39 ms | 902.26 ms |
| Large hall or pad wash | 56.39 ms | 1804.51 ms |
| Ambient tail over two bars | 112.78 ms | 3609.02 ms |
Genres at 133 BPM
133 BPM is squarely in the most common club and dance-music range. It sits in the middle of the UK garage/breakbeat range (125–140), in the middle of the techno range (125–150) and near the low end of the trance range (128–145).
Heard at half-time (66.5 BPM) it lines up with ambient/downtempo. 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.
- UK garage/breakbeat: typically 125–140 BPM — shuffled and broken drums can make the count ambiguous.
- Techno: typically 125–150 BPM — from restrained 125 to fast, hard styles near 150.
- Trance: typically 128–145 BPM — a regular kick usually gives a clear pulse.
Mixing into 133 BPM
To bring a track at another tempo up or down to 133 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 133 BPM reaches 122.4–143.6 BPM; a ±16 % range reaches 111.7–154.3 BPM.
| Track tempo | Pitch change to reach 133 | Key shift without key lock |
|---|---|---|
| 127 BPM | +4.72 % | +0.8 st |
| 129 BPM | +3.1 % | +0.53 st |
| 131 BPM | +1.53 % | +0.26 st |
| 132 BPM | +0.76 % | +0.13 st |
| 134 BPM | −0.75 % | −0.13 st |
| 135 BPM | −1.48 % | −0.26 st |
| 137 BPM | −2.92 % | −0.51 st |
| 139 BPM | −4.32 % | −0.76 st |
Half-time, double-time and nearby tempos
Half-time of 133 BPM is 66.5 BPM and double-time is 266 BPM.
266 BPM is outside the 60–200 range of these pages; the half/double-time converter works with any value.
66.5 BPM falls between two whole tempos, so the nearest pages, 66 and 67 BPM, are linked instead.
Each 1 BPM step at this tempo changes the beat by about 3.37 ms, so neighbouring tempos are close enough to beatmatch with a small pitch move.
Frequently asked questions
- How many milliseconds is one beat at 133 BPM?
- One beat (a quarter note) at 133 BPM is 60,000 ÷ 133 = 451.13 ms. A 4/4 bar is four beats, 1804.51 ms.
- What is the dotted eighth delay time at 133 BPM?
- A dotted 1/8 delay at 133 BPM is 338.35 ms: an eighth note (225.56 ms) multiplied by 1.5. A straight quarter-note delay is 451.13 ms and a quarter-note triplet is 300.75 ms.
- What genre is 133 BPM?
- UK garage/breakbeat, techno and trance commonly use 133 BPM. Genre ranges overlap, so the drum pattern and sound decide the style more than the number does.
- What is 133 BPM in Hz?
- 133 BPM is 2.2167 Hz when one cycle equals one beat. An LFO synced to one bar runs at 0.5542 Hz, and one synced to sixteenth notes at 8.867 Hz.
