Why Mozart was such a succes?

Answer 1

Wolfgang Amadeus Mozart was very talented, and he travelled all over Europe with his equally amazing sister, Nannerl. They preformed for dukes and duchesses, and even kings and queens. And also, Wolfgang's father, Leopold Mozart, was a very famous violinist and composer also; known very well to those of Royalty.

Later, when Europeans discovered North America, they took their tradition, beliefs, and famous people (not literally) over with them.

So this is likely why Wolfgang Amadeus Mozart was "such a sucess", as you say. As a child, as a child...
