What Key? determines the key, or more precisely, the tonality of a song in real time. Combining the spectrum analyzer from Pitch to Note with music theory algorithms, What Key? maps musical notes into the circle of fifths from which the dominant tonality and key can be established. Two screens are provided: one shows the histogram of notes over an interval of time, the other is a probability distribution, with the most probable key identified.
