Beat, bar and phrase lengths at 103 BPM
At 103 BPM one beat lasts 582.52 ms and a 4/4 bar lasts 2.33 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 1.717 beats per second, or 25.75 bars of 4/4 per minute.
Dance tracks are usually arranged in 8-, 16- and 32-bar phrases. At 103 BPM a 16-bar phrase takes 37.28 s and a 32-bar intro or outro takes 1:14.6 min. That is 5.28 s longer than the same 16 bars at 120 BPM. A six-minute track at this tempo contains about 155 bars.
| Length | Time | Milliseconds |
|---|---|---|
| 1 beat | 0.583 s | 582.52 ms |
| 1 bar (4 beats) | 2.33 s | 2330.1 ms |
| 4 bars | 9.32 s | 9320.39 ms |
| 8 bars | 18.64 s | 18640.78 ms |
| 16 bars | 37.28 s | 37281.55 ms |
| 32 bars | 1:14.6 min | 74563.11 ms |
| 64 bars | 2:29.1 min | 149126.21 ms |
Delay times at 103 BPM
Straight values follow the beat; dotted values are 1.5 times as long and triplets are two-thirds as long. At 103 BPM the popular dotted-eighth delay is 436.89 ms and a quarter-note slapback is 582.52 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) | 2330.1 ms | 3495.15 ms | 1553.4 ms | 0.429 Hz |
| 1/2 | 1165.05 ms | 1747.57 ms | 776.7 ms | 0.858 Hz |
| 1/4 (one beat) | 582.52 ms | 873.79 ms | 388.35 ms | 1.717 Hz |
| 1/8 | 291.26 ms | 436.89 ms | 194.17 ms | 3.433 Hz |
| 1/16 | 145.63 ms | 218.45 ms | 97.09 ms | 6.867 Hz |
| 1/32 | 72.82 ms | 109.22 ms | 48.54 ms | 13.733 Hz |
Reverb times at 103 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 103 BPM a 1/64-note pre-delay is 36.41 ms and a 1/32-note pre-delay is 72.82 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 | 36.41 ms | 582.52 ms |
| Medium plate on vocals | 72.82 ms | 1165.05 ms |
| Large hall or pad wash | 72.82 ms | 2330.1 ms |
| Ambient tail over two bars | 145.63 ms | 4660.19 ms |
Genres at 103 BPM
103 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 103 BPM
To bring a track at another tempo up or down to 103 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 103 BPM reaches 94.8–111.2 BPM; a ±16 % range reaches 86.5–119.5 BPM.
| Track tempo | Pitch change to reach 103 | Key shift without key lock |
|---|---|---|
| 97 BPM | +6.19 % | +1.04 st |
| 99 BPM | +4.04 % | +0.69 st |
| 101 BPM | +1.98 % | +0.34 st |
| 102 BPM | +0.98 % | +0.17 st |
| 104 BPM | −0.96 % | −0.17 st |
| 105 BPM | −1.9 % | −0.33 st |
| 107 BPM | −3.74 % | −0.66 st |
| 109 BPM | −5.5 % | −0.98 st |
Half-time, double-time and nearby tempos
Half-time of 103 BPM is 51.5 BPM and double-time is 206 BPM.
51.5 BPM and 206 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 5.6 ms, so neighbouring tempos are close enough to beatmatch with a small pitch move.
Frequently asked questions
- How many milliseconds is one beat at 103 BPM?
- One beat (a quarter note) at 103 BPM is 60,000 ÷ 103 = 582.52 ms. A 4/4 bar is four beats, 2330.1 ms.
- What is the dotted eighth delay time at 103 BPM?
- A dotted 1/8 delay at 103 BPM is 436.89 ms: an eighth note (291.26 ms) multiplied by 1.5. A straight quarter-note delay is 582.52 ms and a quarter-note triplet is 388.35 ms.
- What genre is 103 BPM?
- Pop commonly uses 103 BPM. Genre ranges overlap, so the drum pattern and sound decide the style more than the number does.
- What is 103 BPM in Hz?
- 103 BPM is 1.7167 Hz when one cycle equals one beat. An LFO synced to one bar runs at 0.4292 Hz, and one synced to sixteenth notes at 6.867 Hz.
