Beat, bar and phrase lengths at 143 BPM
At 143 BPM one beat lasts 419.58 ms and a 4/4 bar lasts 1.678 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 2.383 beats per second, or 35.75 bars of 4/4 per minute.
Dance tracks are usually arranged in 8-, 16- and 32-bar phrases. At 143 BPM a 16-bar phrase takes 26.85 s and a 32-bar intro or outro takes 53.71 s. That is 5.15 s shorter than the same 16 bars at 120 BPM. A six-minute track at this tempo contains about 215 bars.
| Length | Time | Milliseconds |
|---|---|---|
| 1 beat | 0.42 s | 419.58 ms |
| 1 bar (4 beats) | 1.678 s | 1678.32 ms |
| 4 bars | 6.713 s | 6713.29 ms |
| 8 bars | 13.43 s | 13426.57 ms |
| 16 bars | 26.85 s | 26853.15 ms |
| 32 bars | 53.71 s | 53706.29 ms |
| 64 bars | 1:47.4 min | 107412.59 ms |
Delay times at 143 BPM
Straight values follow the beat; dotted values are 1.5 times as long and triplets are two-thirds as long. At 143 BPM the popular dotted-eighth delay is 314.69 ms and a quarter-note slapback is 419.58 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) | 1678.32 ms | 2517.48 ms | 1118.88 ms | 0.596 Hz |
| 1/2 | 839.16 ms | 1258.74 ms | 559.44 ms | 1.192 Hz |
| 1/4 (one beat) | 419.58 ms | 629.37 ms | 279.72 ms | 2.383 Hz |
| 1/8 | 209.79 ms | 314.69 ms | 139.86 ms | 4.767 Hz |
| 1/16 | 104.9 ms | 157.34 ms | 69.93 ms | 9.533 Hz |
| 1/32 | 52.45 ms | 78.67 ms | 34.97 ms | 19.067 Hz |
Reverb times at 143 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 143 BPM a 1/64-note pre-delay is 26.22 ms and a 1/32-note pre-delay is 52.45 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 | 26.22 ms | 419.58 ms |
| Medium plate on vocals | 52.45 ms | 839.16 ms |
| Large hall or pad wash | 52.45 ms | 1678.32 ms |
| Ambient tail over two bars | 104.9 ms | 3356.64 ms |
Genres at 143 BPM
143 BPM is in the up-tempo, high-energy range. It sits near the upper end of the techno range (125–150), near the upper end of the trance range (128–145) and near the upper end of the dubstep range (135–145).
Heard at half-time (71.5 BPM) it lines up with ambient/downtempo, hip-hop and reggae/dub. 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.
- 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.
- Dubstep: typically 135–145 BPM — usually counted around 140 but felt at half-time, near 70.
Mixing into 143 BPM
To bring a track at another tempo up or down to 143 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 143 BPM reaches 131.6–154.4 BPM; a ±16 % range reaches 120.1–165.9 BPM.
| Track tempo | Pitch change to reach 143 | Key shift without key lock |
|---|---|---|
| 137 BPM | +4.38 % | +0.74 st |
| 139 BPM | +2.88 % | +0.49 st |
| 141 BPM | +1.42 % | +0.24 st |
| 142 BPM | +0.7 % | +0.12 st |
| 144 BPM | −0.69 % | −0.12 st |
| 145 BPM | −1.38 % | −0.24 st |
| 147 BPM | −2.72 % | −0.48 st |
| 149 BPM | −4.03 % | −0.71 st |
Half-time, double-time and nearby tempos
Half-time of 143 BPM is 71.5 BPM and double-time is 286 BPM.
286 BPM is outside the 60–200 range of these pages; the half/double-time converter works with any value.
71.5 BPM falls between two whole tempos, so the nearest pages, 71 and 72 BPM, are linked instead.
Each 1 BPM step at this tempo changes the beat by about 2.91 ms, so neighbouring tempos are close enough to beatmatch with a small pitch move.
Frequently asked questions
- How many milliseconds is one beat at 143 BPM?
- One beat (a quarter note) at 143 BPM is 60,000 ÷ 143 = 419.58 ms. A 4/4 bar is four beats, 1678.32 ms.
- What is the dotted eighth delay time at 143 BPM?
- A dotted 1/8 delay at 143 BPM is 314.69 ms: an eighth note (209.79 ms) multiplied by 1.5. A straight quarter-note delay is 419.58 ms and a quarter-note triplet is 279.72 ms.
- What genre is 143 BPM?
- Techno, trance and dubstep commonly use 143 BPM. Genre ranges overlap, so the drum pattern and sound decide the style more than the number does.
- What is 143 BPM in Hz?
- 143 BPM is 2.3833 Hz when one cycle equals one beat. An LFO synced to one bar runs at 0.5958 Hz, and one synced to sixteenth notes at 9.533 Hz.
