Funny thing happened to me while studying music theory, after a certain point things stopped making sense to me. I was fine with Intervals, Triads, Seventh Chords, and have even improved my music reading ability, but when I started studying modes I began to feel lost. After reviewing modes a few times, and still not really getting it, I decided to crack open my Teach Me Bass Guitar book to remind myself what Lesson 13 had in store for me. You may recall that upon completion of Lesson 12 I had decided to take a break from TMBG to go back and shore up my music theory knowledge via the International Institute of Bassists Music Theory course as well as a couple of other books that I have picked up along the way. Well, low and behold, what you know, Lesson 13 of TMBG is all about the Diatonic Modes!
