Yes, Mozart has arrived at us in full title and also with full merit, and that is perfectly fine with me.
On how Mozart is venerated today, however, I have many perplexities and reservations; this is the point.
To Kappa I say this: there are composers in music history - even very great ones or, precisely because they were very great - about whom one can say that if they had not existed, not much would have changed from an evolutionary standpoint of the subject matter.
Castaldi says that Mozart was a useless composer and, in large part - though not 100% - I think he is right for the reasons I have already stated.
The uselessness of an artist, however, is not necessarily given only by an evolutionary argument: the function performed by Shostakovich's music within the Soviet historical-political context is very important and, for me, this is very essential.
In a certain sense, something of Mozart's was also so, in a completely different historical context, but this is linked exclusively - or predominantly - to his theater. In short, very little.
Then, as always, our personal tastes certainly come into play and, Mozart is certainly not among my preferences, as has already been clearly understood.
