Sound Reasoning: A New Way to Listen
Really nice “tutorial” on how to listen and appreciate music (mainly focused on western classical music). Requires no formal knowledge of music (or music notation, theory, etc). Lots of audio examples and music excerpts are used to demonstrate the concepts and musical analysis throughout the text (which is really comprehensive).
Highly recommended for anyone interested in learning how to fully appreciate music and all its complexities expressed through sound.
By the way, this “tutorial” is hosted at the excellent Connexions website, where it’s possible to find several other “open source”/wiki-style modules of educational materials. You can even contribute to it!
