Computers exist because of something called the 'Digital abstraction': How
to make a complex messy 'real' thing like voltage into a neat-n-clean
'logical' 0-or-1.

See http://6004.csail.mit.edu/Fall01/handouts/L02-1up.pdf

Musical theory is likewise: Where to put your hands on a guitar or violin
or piano is very different. Musical theory gives an abstract frame where
something essential common to these differences is distilled out.

The question is not so much whether that abstraction is useful so much as
is it faithful.

I recently got into an argument (on the python list so more OT there than
here :-) ) about whether a B# is the same as C. If we allow that they may
not always be the same then we have a case where the
theory-of-musical-harmony (may be) breaking.
