Beat, bar and phrase lengths at 104 BPM
At 104 BPM one beat lasts 576.92 ms and a 4/4 bar lasts 2.308 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 1.733 beats per second, or 26 bars of 4/4 per minute.
Dance tracks are usually arranged in 8-, 16- and 32-bar phrases. At 104 BPM a 16-bar phrase takes 36.92 s and a 32-bar intro or outro takes 1:13.8 min. That is 4.92 s longer than the same 16 bars at 120 BPM. A six-minute track at this tempo contains about 156 bars.
| Length | Time | Milliseconds |
|---|---|---|
| 1 beat | 0.577 s | 576.92 ms |
| 1 bar (4 beats) | 2.308 s | 2307.69 ms |
| 4 bars | 9.231 s | 9230.77 ms |
| 8 bars | 18.46 s | 18461.54 ms |
| 16 bars | 36.92 s | 36923.08 ms |
| 32 bars | 1:13.8 min | 73846.15 ms |
| 64 bars | 2:27.7 min | 147692.31 ms |
Delay times at 104 BPM
Straight values follow the beat; dotted values are 1.5 times as long and triplets are two-thirds as long. At 104 BPM the popular dotted-eighth delay is 432.69 ms and a quarter-note slapback is 576.92 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) | 2307.69 ms | 3461.54 ms | 1538.46 ms | 0.433 Hz |
| 1/2 | 1153.85 ms | 1730.77 ms | 769.23 ms | 0.867 Hz |
| 1/4 (one beat) | 576.92 ms | 865.38 ms | 384.62 ms | 1.733 Hz |
| 1/8 | 288.46 ms | 432.69 ms | 192.31 ms | 3.467 Hz |
| 1/16 | 144.23 ms | 216.35 ms | 96.15 ms | 6.933 Hz |
| 1/32 | 72.12 ms | 108.17 ms | 48.08 ms | 13.867 Hz |
Reverb times at 104 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 104 BPM a 1/64-note pre-delay is 36.06 ms and a 1/32-note pre-delay is 72.12 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 | 36.06 ms | 576.92 ms |
| Medium plate on vocals | 72.12 ms | 1153.85 ms |
| Large hall or pad wash | 72.12 ms | 2307.69 ms |
| Ambient tail over two bars | 144.23 ms | 4615.38 ms |
Genres at 104 BPM
104 BPM is a moderate tempo, a little below the usual club range. It sits in the middle of the pop range (90–130).
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.
Mixing into 104 BPM
To bring a track at another tempo up or down to 104 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 104 BPM reaches 95.7–112.3 BPM; a ±16 % range reaches 87.4–120.6 BPM.
| Track tempo | Pitch change to reach 104 | Key shift without key lock |
|---|---|---|
| 98 BPM | +6.12 % | +1.03 st |
| 100 BPM | +4 % | +0.68 st |
| 102 BPM | +1.96 % | +0.34 st |
| 103 BPM | +0.97 % | +0.17 st |
| 105 BPM | −0.95 % | −0.17 st |
| 106 BPM | −1.89 % | −0.33 st |
| 108 BPM | −3.7 % | −0.65 st |
| 110 BPM | −5.45 % | −0.97 st |
Half-time, double-time and nearby tempos
Half-time of 104 BPM is 52 BPM and double-time is 208 BPM.
52 BPM and 208 BPM are 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 5.49 ms, so neighbouring tempos are close enough to beatmatch with a small pitch move.
Frequently asked questions
- How many milliseconds is one beat at 104 BPM?
- One beat (a quarter note) at 104 BPM is 60,000 ÷ 104 = 576.92 ms. A 4/4 bar is four beats, 2307.69 ms.
- What is the dotted eighth delay time at 104 BPM?
- A dotted 1/8 delay at 104 BPM is 432.69 ms: an eighth note (288.46 ms) multiplied by 1.5. A straight quarter-note delay is 576.92 ms and a quarter-note triplet is 384.62 ms.
- What genre is 104 BPM?
- Pop commonly uses 104 BPM. Genre ranges overlap, so the drum pattern and sound decide the style more than the number does.
- What is 104 BPM in Hz?
- 104 BPM is 1.7333 Hz when one cycle equals one beat. An LFO synced to one bar runs at 0.4333 Hz, and one synced to sixteenth notes at 6.933 Hz.
