Frequently asked questions
Why does my melody fit more than one key?
Relative major and minor keys share the same notes, and neighbouring keys overlap heavily. Use the chord that feels like home, usually where the song resolves, to decide which key is right.
How many notes should I enter to find the key?
The more distinct notes you give, the fewer keys will match. Try at least five or six, and include notes that are surprising or outside a plain scale.
What is the difference between a scale and a key?
A scale is the set of notes in order, while a key tells you which note feels like home and which chords belong with it. C major and A minor share notes but feel different.
