How to Find the Key of a Song

1Identify Notes

Listen to the song and identify the notes used in the melody and chords. Focus on the most prominent notes and the bass notes.

2Select Notes Above

Click on each note you hear in the song. The more notes you identify correctly, the more accurate the key detection will be.

3Review Matches

Check the results. Perfect matches contain all your notes. The "best match" is typically the key, though relative major/minor keys share the same notes.

Pro Tips

  • *The note that feels like "home" or where the song resolves to is usually the root of the key.
  • *If a song sounds happy/bright, it's likely major. If it sounds sad/dark, it's likely minor.
  • *Many songs use notes outside the key (borrowed chords, chromatic passing tones). Start with the most common notes first.
  • *Relative major and minor keys share all the same notes, so both will show as perfect matches. Listen to determine which feels like "home."
