Beat, bar and phrase lengths at 191 BPM
At 191 BPM one beat lasts 314.14 ms and a 4/4 bar lasts 1.257 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 3.183 beats per second, or 47.75 bars of 4/4 per minute.
Dance tracks are usually arranged in 8-, 16- and 32-bar phrases. At 191 BPM a 16-bar phrase takes 20.1 s and a 32-bar intro or outro takes 40.21 s. That is 11.9 s shorter than the same 16 bars at 120 BPM. A six-minute track at this tempo contains about 287 bars.
| Length | Time | Milliseconds |
|---|---|---|
| 1 beat | 0.314 s | 314.14 ms |
| 1 bar (4 beats) | 1.257 s | 1256.54 ms |
| 4 bars | 5.026 s | 5026.18 ms |
| 8 bars | 10.05 s | 10052.36 ms |
| 16 bars | 20.1 s | 20104.71 ms |
| 32 bars | 40.21 s | 40209.42 ms |
| 64 bars | 1:20.4 min | 80418.85 ms |
Delay times at 191 BPM
Straight values follow the beat; dotted values are 1.5 times as long and triplets are two-thirds as long. At 191 BPM the popular dotted-eighth delay is 235.6 ms and a quarter-note slapback is 314.14 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) | 1256.54 ms | 1884.82 ms | 837.7 ms | 0.796 Hz |
| 1/2 | 628.27 ms | 942.41 ms | 418.85 ms | 1.592 Hz |
| 1/4 (one beat) | 314.14 ms | 471.2 ms | 209.42 ms | 3.183 Hz |
| 1/8 | 157.07 ms | 235.6 ms | 104.71 ms | 6.367 Hz |
| 1/16 | 78.53 ms | 117.8 ms | 52.36 ms | 12.733 Hz |
| 1/32 | 39.27 ms | 58.9 ms | 26.18 ms | 25.467 Hz |
Reverb times at 191 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 191 BPM a 1/64-note pre-delay is 19.63 ms and a 1/32-note pre-delay is 39.27 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 | 19.63 ms | 314.14 ms |
| Medium plate on vocals | 39.27 ms | 628.27 ms |
| Large hall or pad wash | 39.27 ms | 1256.54 ms |
| Ambient tail over two bars | 78.53 ms | 2513.09 ms |
Genres at 191 BPM
191 BPM is a very fast tempo, usually heard at half-time unless the style is hardcore. It sits near the upper end of the hardcore/gabber range (160–200).
Heard at half-time (95.5 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 191 BPM
To bring a track at another tempo up or down to 191 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 191 BPM reaches 175.7–206.3 BPM; a ±16 % range reaches 160.4–221.6 BPM.
| Track tempo | Pitch change to reach 191 | Key shift without key lock |
|---|---|---|
| 185 BPM | +3.24 % | +0.55 st |
| 187 BPM | +2.14 % | +0.37 st |
| 189 BPM | +1.06 % | +0.18 st |
| 190 BPM | +0.53 % | +0.09 st |
| 192 BPM | −0.52 % | −0.09 st |
| 193 BPM | −1.04 % | −0.18 st |
| 195 BPM | −2.05 % | −0.36 st |
| 197 BPM | −3.05 % | −0.54 st |
Half-time, double-time and nearby tempos
Half-time of 191 BPM is 95.5 BPM and double-time is 382 BPM.
382 BPM is outside the 60–200 range of these pages; the half/double-time converter works with any value.
95.5 BPM falls between two whole tempos, so the nearest pages, 95 and 96 BPM, are linked instead.
Each 1 BPM step at this tempo changes the beat by about 1.64 ms, so neighbouring tempos are close enough to beatmatch with a small pitch move.
Frequently asked questions
- How many milliseconds is one beat at 191 BPM?
- One beat (a quarter note) at 191 BPM is 60,000 ÷ 191 = 314.14 ms. A 4/4 bar is four beats, 1256.54 ms.
- What is the dotted eighth delay time at 191 BPM?
- A dotted 1/8 delay at 191 BPM is 235.6 ms: an eighth note (157.07 ms) multiplied by 1.5. A straight quarter-note delay is 314.14 ms and a quarter-note triplet is 209.42 ms.
- What genre is 191 BPM?
- Hardcore/gabber commonly uses 191 BPM. Genre ranges overlap, so the drum pattern and sound decide the style more than the number does.
- What is 191 BPM in Hz?
- 191 BPM is 3.1833 Hz when one cycle equals one beat. An LFO synced to one bar runs at 0.7958 Hz, and one synced to sixteenth notes at 12.733 Hz.
