Music Theory for the 21st-Century Classroom
University of Puget Sound
A very popular resource for learning music theory among music students. It is considered quite modern and accessible — the lessons are straight to the point and cover all the basics and a bit beyond that anyone would want to know about music theory. I have been using this material to better understand the logic behind the pieces I have been learning on piano and clarinet.
