What is a "key profile"?
Krumhansl-Schmuckler developed an algorithm that aids in finding the key of a piece of music.
The algorithm depends on pitches and durations and requires the generation of a key profile.
What is a C-major key profile and a C-minor key profile?
I need to fill a 12-bit vector with such a key profile so I can compare it to 12 chromatic pitches in a given scale. C major and C minor scales have just 7 notes.
