Beat, bar and phrase lengths at 166 BPM
At 166 BPM one beat lasts 361.45 ms and a 4/4 bar lasts 1.446 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 2.767 beats per second, or 41.5 bars of 4/4 per minute.
Dance tracks are usually arranged in 8-, 16- and 32-bar phrases. At 166 BPM a 16-bar phrase takes 23.13 s and a 32-bar intro or outro takes 46.27 s. That is 8.87 s shorter than the same 16 bars at 120 BPM. A six-minute track at this tempo contains about 249 bars.
| Length | Time | Milliseconds |
|---|---|---|
| 1 beat | 0.361 s | 361.45 ms |
| 1 bar (4 beats) | 1.446 s | 1445.78 ms |
| 4 bars | 5.783 s | 5783.13 ms |
| 8 bars | 11.57 s | 11566.27 ms |
| 16 bars | 23.13 s | 23132.53 ms |
| 32 bars | 46.27 s | 46265.06 ms |
| 64 bars | 1:32.5 min | 92530.12 ms |
Delay times at 166 BPM
Straight values follow the beat; dotted values are 1.5 times as long and triplets are two-thirds as long. At 166 BPM the popular dotted-eighth delay is 271.08 ms and a quarter-note slapback is 361.45 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) | 1445.78 ms | 2168.67 ms | 963.86 ms | 0.692 Hz |
| 1/2 | 722.89 ms | 1084.34 ms | 481.93 ms | 1.383 Hz |
| 1/4 (one beat) | 361.45 ms | 542.17 ms | 240.96 ms | 2.767 Hz |
| 1/8 | 180.72 ms | 271.08 ms | 120.48 ms | 5.533 Hz |
| 1/16 | 90.36 ms | 135.54 ms | 60.24 ms | 11.067 Hz |
| 1/32 | 45.18 ms | 67.77 ms | 30.12 ms | 22.133 Hz |
Reverb times at 166 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 166 BPM a 1/64-note pre-delay is 22.59 ms and a 1/32-note pre-delay is 45.18 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 | 22.59 ms | 361.45 ms |
| Medium plate on vocals | 45.18 ms | 722.89 ms |
| Large hall or pad wash | 45.18 ms | 1445.78 ms |
| Ambient tail over two bars | 90.36 ms | 2891.57 ms |
Genres at 166 BPM
166 BPM is a fast tempo that is often felt at half-time. It sits in the middle of the drum and bass range (160–180) and near the low end of the hardcore/gabber range (160–200).
Heard at half-time (83 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.
- Drum and bass: typically 160–180 BPM — modern releases mostly sit at 170–176; often felt at half-time.
- Hardcore/gabber: typically 160–200 BPM — speedcore and some gabber go well beyond 200.
Mixing into 166 BPM
To bring a track at another tempo up or down to 166 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 166 BPM reaches 152.7–179.3 BPM; a ±16 % range reaches 139.4–192.6 BPM.
| Track tempo | Pitch change to reach 166 | Key shift without key lock |
|---|---|---|
| 160 BPM | +3.75 % | +0.64 st |
| 162 BPM | +2.47 % | +0.42 st |
| 164 BPM | +1.22 % | +0.21 st |
| 165 BPM | +0.61 % | +0.1 st |
| 167 BPM | −0.6 % | −0.1 st |
| 168 BPM | −1.19 % | −0.21 st |
| 170 BPM | −2.35 % | −0.41 st |
| 172 BPM | −3.49 % | −0.61 st |
Half-time, double-time and nearby tempos
Half-time of 166 BPM is 83 BPM and double-time is 332 BPM.
332 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 2.16 ms, so neighbouring tempos are close enough to beatmatch with a small pitch move.
Frequently asked questions
- How many milliseconds is one beat at 166 BPM?
- One beat (a quarter note) at 166 BPM is 60,000 ÷ 166 = 361.45 ms. A 4/4 bar is four beats, 1445.78 ms.
- What is the dotted eighth delay time at 166 BPM?
- A dotted 1/8 delay at 166 BPM is 271.08 ms: an eighth note (180.72 ms) multiplied by 1.5. A straight quarter-note delay is 361.45 ms and a quarter-note triplet is 240.96 ms.
- What genre is 166 BPM?
- Drum and bass and hardcore/gabber commonly use 166 BPM. Genre ranges overlap, so the drum pattern and sound decide the style more than the number does.
- What is 166 BPM in Hz?
- 166 BPM is 2.7667 Hz when one cycle equals one beat. An LFO synced to one bar runs at 0.6917 Hz, and one synced to sixteenth notes at 11.067 Hz.
