How to find the BPM of a song
BPM (beats per minute) is a song's tempo. You need it to DJ, remix, sample, or set your DAW grid. Here are three ways to find it, from fastest to most manual.
Step by step
- Upload the song to a BPM finder. Drop an MP3 or WAV into Sonar's free Key & BPM Finder. It listens to the kick, snare and hi-hats and gives you the tempo in a few seconds, right in your browser.
- Check half-time and double-time. Trap at 140 can feel like 70; drum & bass at 174 can feel like 87. The finder shows both numbers so you can pick the one that matches how the song feels.
- Confirm by tapping. Tap along to the beat in any tap-tempo tool or your DAW for 10–15 seconds. If your tapped number is within 1–2 BPM, you have it.
- Or count it yourself. Count kick drums for 15 seconds and multiply by 4. It's rough, but works anywhere with no tools.
Songs recorded live without a click can drift a few BPM. Use the average from the main chorus, not the intro.
Why BPM finders sometimes disagree
Most disagreements are octave errors: one tool says 87, another says 174. Both describe the same pulse. Pick the number that matches where a listener would naturally nod their head, or the one your genre usually uses (house sits at 120–128, hip-hop at 80–100 or 140–160 in half-time).
Sparse intros, tempo changes and swing can also confuse detection. If a result looks off, trim the file to a full chorus and run it again.
Common questions
- What is the easiest way to find a song's BPM?
- Upload the file to a free online BPM finder such as Sonar's Key & BPM Finder. It analyzes the beat and returns the tempo in seconds with no account needed.
- Can I find the BPM of a song on Spotify?
- Spotify doesn't show BPM in its app. Use the audio file you have with a BPM finder, or tap along to the song while it plays.
- Is the BPM always a whole number?
- Produced tracks are almost always set to a whole number. Live recordings can sit between numbers or drift; finders round to the nearest whole BPM.
