If you’ve always wanted to beef up your knowledge of the basic nuts and bolts of music, you might want to check out the latest MOOC (“massive open online course”) from Berklee College of Music:  Developing Your Musicianship.

The course starts on April 1st (no foolin’!), but registration is open now. It’s totally free, suitable for all instruments, and you can drop the class at any time if you decide it’s not up your alley.
