HES: QUERY--Mill and music

[Carlos Rodriguez Braun]

I remember the Argentine writer Jorge Luis Borges saying that according to 
John Stuart Mill the composition of music will eventually come to an end, 
because the number of combinations of seven notes is finite. I have never 
heard or read about a similar idea by another author, but neither have I 
come accross this theory in Mill's own writings. Does anyone have a clue on 
this matter?
