How to use Detect BPM, Key & Chords
- Load a song or loop with a clear beat and pitched instruments. Select Detect BPM, key & chords.
- Check the estimated tempo against the audible pulse and read the key as the main major or minor tonal center.
- Cue chord changes on the timeline and compare them by ear. If you only care about one section of a song with tempo or key changes, analyze a trimmed copy of that section.
Frequently asked questions
Why is the tempo half or double what I expected?
The same accents can suggest different beat groupings. For example, 70 BPM and 140 BPM can both fit the same recording. Count where the strong beats and bar lines feel natural.
Why does the tool report an unclear key or chord?
A drum loop, sparse arrangement or changing harmony may provide too little evidence. The tool estimates major and minor chords, so complex voicings can appear as a simpler chord or remain unclear.
What tempo range does it analyze?
It looks for a steady pulse from 55 to 210 BPM. A performance that drifts in tempo may work better if you analyze a shorter section.
