Hi all,

In my music study, I've been learning to analyze and hear what key a song is in, modulations to other keys, substitute chords, etc. The rules take some decision making - but for the most part they are applied in structured ways, ways that can be programmed.

Has anyone run across a program that can do this, or is there nothing like it yet ?

P.S. - I would find it extremely helpful, in my study of theory, to have BB songs that list such information under the scores - is there any way to have this type of information displayed, or to look into selected files to extract it oneself ?
