How fast is 170 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.
170 BPM means 170 beats pass every minute. One beat lasts 352.9 milliseconds (0.353 seconds); counted in 4/4 a bar takes 1.41 seconds, so about 42.5 bars go by each minute. Over a three-minute song that is roughly 128 bars, or 510 beats.
A resting pulse sits around 60–80 beats per minute, so 170 BPM is roughly 2.4 times faster.
170 BPM is the lower edge of drum and bass, where liquid styles tend to sit.
Note lengths at 170 BPM
Here is what each note value actually measures at 170 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) | 1411.8 ms | 42.5 |
| Half note (2 beats) | 705.9 ms | 85 |
| Quarter note (1 beat) | 352.9 ms | 170 |
| Dotted eighth note | 264.7 ms | 226.7 |
| Eighth-note triplet | 117.6 ms | 510 |
| Eighth note | 176.5 ms | 340 |
| Sixteenth note | 88.2 ms | 680 |
How to practise at 170 BPM
If this tempo is still out of reach, climb to it in three steps. Start at 119 BPM (70% of target) where you can watch what your hands are doing, move to 145 BPM (85%) to balance the sound, then go to 170 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 187 BPM for a few passes and drop back — 170 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 170 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 170 BPM?
One beat lasts 352.9 milliseconds, or 0.353 seconds. A bar of 4/4 takes 1.41 seconds, an eighth note is 176.5 ms and a sixteenth note is 88.2 ms.
What tempo marking is 170 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 170 BPM feels too fast?
Slowing down is not losing ground; it is buying accuracy. Work up from 119 BPM through 145 BPM to 170 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.
How do I feel 170 BPM in half-time?
Set the click to 85 BPM and count eighth notes between the clicks. With half the clicks, your own timing has to fill the gaps, which is exactly why half-time practice exposes drift that a 170 BPM click would have hidden.
