Beat, bar and phrase lengths at 187 BPM
At 187 BPM one beat lasts 320.86 ms and a 4/4 bar lasts 1.283 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 3.117 beats per second, or 46.75 bars of 4/4 per minute.
Dance tracks are usually arranged in 8-, 16- and 32-bar phrases. At 187 BPM a 16-bar phrase takes 20.53 s and a 32-bar intro or outro takes 41.07 s. That is 11.47 s shorter than the same 16 bars at 120 BPM. A six-minute track at this tempo contains about 281 bars.
| Length | Time | Milliseconds |
|---|---|---|
| 1 beat | 0.321 s | 320.86 ms |
| 1 bar (4 beats) | 1.283 s | 1283.42 ms |
| 4 bars | 5.134 s | 5133.69 ms |
| 8 bars | 10.27 s | 10267.38 ms |
| 16 bars | 20.53 s | 20534.76 ms |
| 32 bars | 41.07 s | 41069.52 ms |
| 64 bars | 1:22.1 min | 82139.04 ms |
Delay times at 187 BPM
Straight values follow the beat; dotted values are 1.5 times as long and triplets are two-thirds as long. At 187 BPM the popular dotted-eighth delay is 240.64 ms and a quarter-note slapback is 320.86 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) | 1283.42 ms | 1925.13 ms | 855.61 ms | 0.779 Hz |
| 1/2 | 641.71 ms | 962.57 ms | 427.81 ms | 1.558 Hz |
| 1/4 (one beat) | 320.86 ms | 481.28 ms | 213.9 ms | 3.117 Hz |
| 1/8 | 160.43 ms | 240.64 ms | 106.95 ms | 6.233 Hz |
| 1/16 | 80.21 ms | 120.32 ms | 53.48 ms | 12.467 Hz |
| 1/32 | 40.11 ms | 60.16 ms | 26.74 ms | 24.933 Hz |
Reverb times at 187 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 187 BPM a 1/64-note pre-delay is 20.05 ms and a 1/32-note pre-delay is 40.11 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 | 20.05 ms | 320.86 ms |
| Medium plate on vocals | 40.11 ms | 641.71 ms |
| Large hall or pad wash | 40.11 ms | 1283.42 ms |
| Ambient tail over two bars | 80.21 ms | 2566.84 ms |
Genres at 187 BPM
187 BPM is a very fast tempo, usually heard at half-time unless the style is hardcore. It sits in the middle of the hardcore/gabber range (160–200).
Heard at half-time (93.5 BPM) it lines up with ambient/downtempo, hip-hop, reggae/dub, reggaeton/dembow and pop. 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.
- Hardcore/gabber: typically 160–200 BPM — speedcore and some gabber go well beyond 200.
Mixing into 187 BPM
To bring a track at another tempo up or down to 187 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 187 BPM reaches 172–202 BPM; a ±16 % range reaches 157.1–216.9 BPM.
| Track tempo | Pitch change to reach 187 | Key shift without key lock |
|---|---|---|
| 181 BPM | +3.31 % | +0.56 st |
| 183 BPM | +2.19 % | +0.37 st |
| 185 BPM | +1.08 % | +0.19 st |
| 186 BPM | +0.54 % | +0.09 st |
| 188 BPM | −0.53 % | −0.09 st |
| 189 BPM | −1.06 % | −0.18 st |
| 191 BPM | −2.09 % | −0.37 st |
| 193 BPM | −3.11 % | −0.55 st |
Half-time, double-time and nearby tempos
Half-time of 187 BPM is 93.5 BPM and double-time is 374 BPM.
374 BPM is outside the 60–200 range of these pages; the half/double-time converter works with any value.
93.5 BPM falls between two whole tempos, so the nearest pages, 93 and 94 BPM, are linked instead.
Each 1 BPM step at this tempo changes the beat by about 1.71 ms, so neighbouring tempos are close enough to beatmatch with a small pitch move.
Frequently asked questions
- How many milliseconds is one beat at 187 BPM?
- One beat (a quarter note) at 187 BPM is 60,000 ÷ 187 = 320.86 ms. A 4/4 bar is four beats, 1283.42 ms.
- What is the dotted eighth delay time at 187 BPM?
- A dotted 1/8 delay at 187 BPM is 240.64 ms: an eighth note (160.43 ms) multiplied by 1.5. A straight quarter-note delay is 320.86 ms and a quarter-note triplet is 213.9 ms.
- What genre is 187 BPM?
- Hardcore/gabber commonly uses 187 BPM. Genre ranges overlap, so the drum pattern and sound decide the style more than the number does.
- What is 187 BPM in Hz?
- 187 BPM is 3.1167 Hz when one cycle equals one beat. An LFO synced to one bar runs at 0.7792 Hz, and one synced to sixteenth notes at 12.467 Hz.
