How does it work?

It measures how much of each of the 12 notes sounds through the track and compares that profile with every major and minor key.

Why is the second key so close?

Relative keys (for example C major and A minor) share the same notes. Listen to which note feels like "home" to choose.

Is my file uploaded?
