Find a song's key and BPM

Drop a file, type a song's name, paste a link, or let the Key finder listen, and get the key, BPM and chords.

Get the key and tempo of any song in a few seconds, from whatever you have.

From a file

  1. Open the Key finder.
  2. Press Upload, or drop the file on the page. Acapellas, instrumentals and full songs all work.
  3. The key and BPM show on the track, and the waveform is coloured by key. If the song changes key, each key is printed where it starts.

For anything up to a minute, such as a loop or a sample, the chords also show under the waveform. Press a chord to hear it.

  1. Type the song's name, or paste a Spotify, Apple Music, YouTube, SoundCloud, Deezer or smart link, in the Song name or link field.
  2. Each result shows its key and BPM. Press one, or press Enter for the first, to add it.

You don't need the audio. To hear the song in the playlist later, drop its file on its lane.

By listening

  1. Press Listen and choose Microphone, or Tab or screen audio to hear a song playing on your computer (Chrome, Edge and the desktop app).
  2. Play or sing something. The first key shows within about two seconds, and the wheel follows the music as it changes.
  3. Press Stop listening when you're done.

Pick up where you left off

The keys and songs you looked at last sit under Recent. Press one to go back to it. They stay in your browser, and Clear empties the list.

Save a track to Aden

Open a track's … menu and choose Save as track. Aden opens on a new track with the file, title, BPM and key filled in.
