Status Updates From Music in Theory and Practice

I had just commented to my children (who were choosing next year's high-school classes) that I'd always wished I'd taken a music theory class, when I came across this textbook for 25 cents at a thrift shop. I saw it as an opportunity to teach myself!

I do wish the answers to the exercises were in the back -- I may be teaching myself, but I don't have the teachers' edition.
