What Key Is This Progression Actually In?
Most key finders match scales and give you a confident-looking answer. Fretscape asks what the progression actually suggests - and tells you how sure it is.

The Wrong Name, Ranked First
Hand a reverse chord lookup three notes and it leads with C6(no3) over the obvious Am7 - then warns about its own answer. Lookup isn't the problem. Ranking is.
