How fast is 173 BPM?
Technique goals usually live in this range. Getting there by naming a target and forcing it is slower, in practice, than adding a few BPM at a time to a tempo you already play cleanly.
173 BPM means 173 beats pass every minute. One beat lasts 346.8 milliseconds (0.347 seconds); counted in 4/4 a bar takes 1.39 seconds, so about 43.3 bars go by each minute. Over a three-minute song that is roughly 130 bars, or 519 beats.
A resting pulse sits around 60–80 beats per minute, so 173 BPM is roughly 2.5 times faster.
Note lengths at 173 BPM
Here is what each note value actually measures at 173 BPM. It is the table to check before subdivision practice, and the one producers reach for when setting time-based effects.
| Note value | Length | Per minute |
|---|---|---|
| Whole note (4 beats) | 1387.3 ms | 43.3 |
| Half note (2 beats) | 693.6 ms | 86.5 |
| Quarter note (1 beat) | 346.8 ms | 173 |
| Dotted eighth note | 260.1 ms | 230.7 |
| Eighth-note triplet | 115.6 ms | 519 |
| Eighth note | 173.4 ms | 346 |
| Sixteenth note | 86.7 ms | 692 |
How to practise at 173 BPM
If this tempo is still out of reach, climb to it in three steps. Start at 121 BPM (70% of target) where you can watch what your hands are doing, move to 147 BPM (85%) to balance the sound, then go to 173 BPM. Only move up when you have played the passage five times in a row without a mistake. If the tempo is already comfortable, push to 190 BPM for a few passes and drop back — 173 BPM will feel roomy afterwards.
Turn subdivision off up here and keep only the large beats. A click that dense reads as a wall of sound and stops being a reference at all. Accent the first beat of the bar only, then check after eight bars whether you are still with it.
Music that sits at 173 BPM
The faster the genre, the more likely the groove is decided at half speed. The snare in a 174 BPM track lands on an 87 BPM pulse.
- Drum and bass (170–176 BPM)
- Up-tempo ska and rocksteady
- Hardcore punk (180 BPM and up)
- Bluegrass and Irish reels
- Fast final movements in classical repertoire
Frequently asked questions
How long is one beat at 173 BPM?
One beat lasts 346.8 milliseconds, or 0.347 seconds. A bar of 4/4 takes 1.39 seconds, an eighth note is 173.4 ms and a sixteenth note is 86.7 ms.
What tempo marking is 173 BPM?
The 160–199 BPM range is usually labelled Presto. Those boundaries were never fixed — different eras and composers used the terms differently — so treat the name as a description of character and the number as the measurement.
What if 173 BPM feels too fast?
Slowing down is not losing ground; it is buying accuracy. Work up from 121 BPM through 147 BPM to 173 BPM. Anything you repeat at a tempo where you make mistakes gets learned along with the mistakes, so the fastest tempo you can play cleanly is the tempo worth practising at.
