IMHO, use a dictionary with tuple keys:

notes = {
            ('E',4): 4,
            ('F',2): 4
            }

and so on. If you need more than one piece of info attached to each note, use 
a tuple.  I gather that you mean for this to map to a quality score that your 
algorithm is going to use to select notes.

I would also use a mechanism like this to map the note identification tuple 
to the means of producing the notes. This could be standard arguments for a 
MIDI driver function or even (more advanced, but possibly more flexible) a 
lambda or defined function to call the driver (in the latter case a "factory" 
class generating callable instances is actually better than a straight 
function).  This is more flexible, because you can easily alter the factory 
to support alternate backend actions: play the MIDI, play on your sound card, 
write the data to disk, drive a musical notation generator like MusicTeX, and 
so on.

Cheers,
Terry
