How to Find the Key of a Song

Option 1: A key finder

Drop the file into the Song Key Finder. It analyses the audio in your browser and shows the likely key. Nothing is uploaded.

Option 2: By ear

1. Play the song and hum along until you find the note that feels like the resting place. That is the root.
2. Play that note on a keyboard and compare. Check if the song sounds bright (major) or darker (minor).
3. Check the first and last chords of the song. They are often the key’s chord.

Why it matters

A pitch tool needs the key to tell wrong notes from right ones. Singers also need the key to check if a song fits their voice.

Limits

Songs that change key or use unusual scales confuse key finders. Treat the result as a strong suggestion and confirm by ear.
