the influence of AMADEUS in Solo con tu pareja

When you watch Solo con tu pareja (1991), you will arrive at the moment when the protagonist encounters the last girl he will ever want.
She is in bed, he is outside the window on a ledge, watching her.
The music of Mozart begins in the film.
My ears flood with the words of F. Murray Abraham (Amadeus 1984) describing the same music the protagonist in Solo con tu pareja, is feeling while watching the girl.
These words played back in my head while watching that scene:

Then suddenly - high above it - an oboe, a single note, hanging there unwavering, till a clarinet took over and sweetened it into a phrase of such delight! This was no composition by a performing monkey! This was a music I'd never heard. Filled with such longing, such unfulfillable longing, it had me trembling. It seemed to me that I was hearing the very voice of God.

It is interesting to me simply because Amadeus is such a masterpiece that itself has become an entity, besides Mozart's music, able to inspire independently!
