Rimsky-Korsakov's "Principles of Orchestration" is one of the finest orchestration books ever published. This online interactive edition presents this classic work as a multimedia, self paced course, delivered on the Northern Sounds forum.
It is our pleasure to emphasize that the course is free. There is no charge, direct or hidden, no registration required, no book to buy, no obligation and no strings attached. Just come and learn!
The course has 26 lessons with numerous interactive scores (275 of them) that allow you to see the score while you hear the music. There are also exercises with scores, midi files and audio clips. There are online orchestration professors and a community learning environment where learners can discuss the topics and share their examples. Here's the link to the course itself: http://www.northernsounds.com/forum/...splay.php?f=77
We are almost finished with the first run of the course. Only one lesson remains and then a wrap up.
