There are a couple of digital music courses on Coursera, one that just ended (but is archived) and another coming up in October:
* Introduction to Digital Sound Design (https://www.coursera.org/course/digitalsounddesign)
* Introduction to Programming for Digital Artists (https://www.coursera.org/course/chuck101) (yep, this is for music)
You are getting great advice. Pick one thing and do it for 10 minutes.
