I bow to your superior experience in such matters.
Beethoven, of course, developed a very finely tuned mental model of
sound and conscious response to sound during the time he could hear.
Did he? Do you have evidence of this, or is it just more of your
baseless presumption? Some consider that he produced his finest work
*after* he became deaf, which is somewhat contrary to your assertion.
if you think that is contrary to my assertion, you are revealing your
ignorance of how composers work. Like many composers, Beethoven had a
"mental model" of sound.he could read a score and imagine how it
sounded --- and he must have been able to do this accurately in order
to produce great music after he went deaf. He got better at writing
scores through his whole life --- but it is unlikely his mental model
of sound got more accurate after he went deaf. In fact, some
commentators have pointed to specifi awkward
moments which Beethoven may have wanted to revise if he could have
heard them.
