In addition to these websites, I recommend this workbook series to my students as a "painless" way to begin learning music theory. There are three volumes: Beginning Theory, Intermediate Theory and Advanced Theory, and they are very non-threatening. The three volumes stacked together measure less than three-eighths of an inch thick. The price is non-threatening, too. Each volume costs less than five dollars.
