Entropy and music

Requiem - Mozart is now playing on Uher 4200 but in reverse.


Harmonicprogressionwise it sounds nonsense, as if the composition is made by someone with no talent.


Yet it is the same chords, same key, everything put in reverse order, backwards in time.


The arrow of time ie entropy is reversed.


But what happens in music?


Normally 7ths and 9ths are prepared, (played in advance) for preparing the human brain [Bach, Niedt).


In reverse this is not the case.


Could Bach, Niedt rules indicate entropy in music?


They surely indicate arrow of time. If one does not know the correct direction in a score, it can be found even without listening by observing the rule of prepared dissonant intervals and then the third with respect to bass added for the human brain so that they sound fabulous.


Is talent related to entropy?


Strangely enough there is a section on the Requiem's introduction which sounds quiet similar backwards in time to the original.
