How to Detect Musical Keys

Identify any musical key to find its Open Key code, relative major/minor, and scale notes.

Determining properties of a key simplifies songwriting and harmonic mixing.

  • Type a key signature like 'Am' (A minor), 'c#' (C# minor/Db minor), or 'G' (G major).
  • Our engine immediately detects flats, sharps, case sensitivity, and maps it.
  • Find the Scale Notes representing the tones forming the key's basis.
  • See the Relative Key Partner, which contains identical building pitches (useful for key shifting).
  • Refer to the interactive Circle of Fifths Circle highlighting where the key sits on the pitch constellation.

Frequently Asked Questions

What is a relative major or minor key?
Relative keys share the exact same scale notes (key signature) but have a different starting point (root note). For instance, A Minor and C Major are relatives.
Can I enter flat or sharp key names?
Yes! You can enter keys using sharps (e.g., C#, F#m) or flats (e.g., Db, Ebm).
