Beat, bar and phrase lengths at 124 BPM
At 124 BPM one beat lasts 483.87 ms and a 4/4 bar lasts 1.935 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 2.067 beats per second, or 31 bars of 4/4 per minute.
Dance tracks are usually arranged in 8-, 16- and 32-bar phrases. At 124 BPM a 16-bar phrase takes 30.97 s and a 32-bar intro or outro takes 1:01.9 min. That is 1.03 s shorter than the same 16 bars at 120 BPM. A six-minute track at this tempo contains about 186 bars.
| Length | Time | Milliseconds |
|---|---|---|
| 1 beat | 0.484 s | 483.87 ms |
| 1 bar (4 beats) | 1.935 s | 1935.48 ms |
| 4 bars | 7.742 s | 7741.94 ms |
| 8 bars | 15.48 s | 15483.87 ms |
| 16 bars | 30.97 s | 30967.74 ms |
| 32 bars | 1:01.9 min | 61935.48 ms |
| 64 bars | 2:03.9 min | 123870.97 ms |
Delay times at 124 BPM
Straight values follow the beat; dotted values are 1.5 times as long and triplets are two-thirds as long. At 124 BPM the popular dotted-eighth delay is 362.9 ms and a quarter-note slapback is 483.87 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) | 1935.48 ms | 2903.23 ms | 1290.32 ms | 0.517 Hz |
| 1/2 | 967.74 ms | 1451.61 ms | 645.16 ms | 1.033 Hz |
| 1/4 (one beat) | 483.87 ms | 725.81 ms | 322.58 ms | 2.067 Hz |
| 1/8 | 241.94 ms | 362.9 ms | 161.29 ms | 4.133 Hz |
| 1/16 | 120.97 ms | 181.45 ms | 80.65 ms | 8.267 Hz |
| 1/32 | 60.48 ms | 90.73 ms | 40.32 ms | 16.533 Hz |
Reverb times at 124 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 124 BPM a 1/64-note pre-delay is 30.24 ms and a 1/32-note pre-delay is 60.48 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 | 30.24 ms | 483.87 ms |
| Medium plate on vocals | 60.48 ms | 967.74 ms |
| Large hall or pad wash | 60.48 ms | 1935.48 ms |
| Ambient tail over two bars | 120.97 ms | 3870.97 ms |
Genres at 124 BPM
124 BPM is squarely in the most common club and dance-music range. It sits near the upper end of the pop range (90–130), near the upper end of the disco range (105–130) and in the middle of the house range (118–130).
Heard at half-time (62 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.
- Pop: typically 90–130 BPM — a wide band; the genre is defined by songwriting, not tempo.
- Disco: typically 105–130 BPM — steady four-on-the-floor sections are easy to count.
- House: typically 118–130 BPM — most club house clusters around 120–128.
Mixing into 124 BPM
To bring a track at another tempo up or down to 124 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 124 BPM reaches 114.1–133.9 BPM; a ±16 % range reaches 104.2–143.8 BPM.
| Track tempo | Pitch change to reach 124 | Key shift without key lock |
|---|---|---|
| 118 BPM | +5.08 % | +0.86 st |
| 120 BPM | +3.33 % | +0.57 st |
| 122 BPM | +1.64 % | +0.28 st |
| 123 BPM | +0.81 % | +0.14 st |
| 125 BPM | −0.8 % | −0.14 st |
| 126 BPM | −1.59 % | −0.28 st |
| 128 BPM | −3.12 % | −0.55 st |
| 130 BPM | −4.62 % | −0.82 st |
Half-time, double-time and nearby tempos
Half-time of 124 BPM is 62 BPM and double-time is 248 BPM.
248 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 3.87 ms, so neighbouring tempos are close enough to beatmatch with a small pitch move.
Frequently asked questions
- How many milliseconds is one beat at 124 BPM?
- One beat (a quarter note) at 124 BPM is 60,000 ÷ 124 = 483.87 ms. A 4/4 bar is four beats, 1935.48 ms.
- What is the dotted eighth delay time at 124 BPM?
- A dotted 1/8 delay at 124 BPM is 362.9 ms: an eighth note (241.94 ms) multiplied by 1.5. A straight quarter-note delay is 483.87 ms and a quarter-note triplet is 322.58 ms.
- What genre is 124 BPM?
- Pop, disco and house commonly use 124 BPM. Genre ranges overlap, so the drum pattern and sound decide the style more than the number does.
- What is 124 BPM in Hz?
- 124 BPM is 2.0667 Hz when one cycle equals one beat. An LFO synced to one bar runs at 0.5167 Hz, and one synced to sixteenth notes at 8.267 Hz.
