I've read bits about Mozart and h ve seen the film Amadeus but never read an explicit biography of the author. I chose this book mainly because it's printed in 1906 and I just really like reading such an old copy, and I don't regret it at all. 
 
It's a decent biography, the 2-part structure of the book is a good idea. A third of the book is essentially a traditional biography, looking at his childhood, where he went, who he interacted with and so on. Then the next 2 thirds almost entirely look at his music, and how it evolved over the years, with a shorter biographical third section at the end. 
 
The writing can feel a bit dry sometimes without much emotion coming through from the author, however it's not always the case and you can have a little chuckle here and there while reading this. In the end I learned a few things that were interesting, and this book looks pretty on my shelf so I can't complain
