Frequently asked questions
How accurate is the BPM and key detection?
BPM and key data comes directly from Spotify's audio analysis, which uses professional-grade algorithms to analyze the full audio waveform. BPM accuracy is typically within 1 BPM of the actual tempo. Key detection is correct for the vast majority of tracks, though songs with key changes or ambiguous tonality may show the dominant key rather than every key used.
What is Camelot notation and how do I use it?
Camelot notation assigns every musical key a number (1-12) and a letter (A for minor, B for major). To mix harmonically, move one number up or down, or switch between A and B at the same number. For example, from 5A (F Minor) you can safely mix into 4A, 6A, or 5B. This system is used by Rekordbox, Traktor, Mixed In Key, and most professional DJ software.
Can I look up multiple tracks at once?
This tool looks up one track at a time for maximum accuracy. If you need batch BPM and key analysis for a whole set or playlist, run an Instagram or SoundCloud analysis — it detects key and BPM for every track it discovers automatically. You get 3 free analyses per month; after that, credits are $4.99 for 10, one-time, no subscription.
What if the track isn't on Spotify?
If a track is not in Spotify's catalog (common for white labels, unreleased edits, or Bandcamp-only releases), the lookup will return no results. In that case, you can use DJ software like Rekordbox or Traktor to analyze the audio file directly, or try a slight variation of the track title. Many underground tracks are listed under different spellings or remix names.
