Hi People,
I've just come across this website:
http://dme.mozarteum.at/
It contains the complete works (as sheet music) of one: Johannes Chrysostomus Wolfgangus Theophilus Mozart
(Beter known today as Wolfgang Amadeus Mozart)
It's official, free, and legal. How cool is that!?

Very important site!. And it has the complete scores, not piano reductions.

The copies on that site are available under licence for restricted use "for personal study and for educational and classroom use". A significant proportion of the editions are still subject to copyright restrictions - so that arrangements and adaptations require permission etc.

Personally, I am very encouraged to see the opportunity to browse such music and I hope to see similar sites for other composers.

I found that site myself. I just haven't taken the time to try and figure out what pieces might be on flute for it since it is all in German. Has anyone else found flute only music there?

There is a button right on the top of the page that says English.

Cool, thanks!
