Question on BYCU lesson 16 exercise in sixths

Hi Piper19,

First of all, thanks for your kind words. I'm always glad to hear that my books are helpful.

With regard to the 6ths: I have to work up a diagram that will help you to see how they work. That's something I wish I would have done when I first wrote BYCU. Keep looking in, I'll get it up in the near future.

One last note: whatever kind of music you play, you do have to think about what you're doing. But it's fun.

James,

Welcome to the forum. We need some new blood around here. I'm not sure what your question is precisely. Are you confused over what is meant by the term "6th's" or where they lay on the finger board or something else? If you could reformulate your question I'm sure somebody here can answer it. We've all been through this at one time.

If you are on Lesson 16 then you're starting to see some light at the end of the tunnel. I hope you become a regular participant here. We share a lot of good information and try to help each other out.

I think the 6th interval comes from the top and bottom notes of triad inversions. Here's an article on triad inversions: www.premierguitar.com/articles/Deep_Blues_Blue_Triads

He shows the same A7, D7 E7 progression that's on page 67 of the book, and if you look at the fretboard diagrams you can see how the notes on page 67 correspond to the top and bottom notes of those triad inversions. The guy's explanation of how he builds those triads is long and involved though

Maybe a simpler way to think about it would be as a chord scale idea.  Those dominant 7th chords on page 67 have a root, major third, 5th and minor 7th, which corresponds to the Mixolydian mode.  If you go to a scale generator:  www.guitarmasterclass.net/scalegenerator/  and bring up the A Moxilyian mode (hit "all" under "positions" to see the whole fretboard) you'll see that all the notes for the A7 chord on page 67 correspond to notes from that mode.  Some are going to be notes from the chord, and other just fit the sound because that mode is built from the same notes as the chord.  And the notes of D and E Mixolydian are going to correspond to the other two chords on page 67.  You can kind of figure out which pairs of notes are a 6th apart and go from there.

Of course other types of chords would correspond to other scales - major chords would correspond to the major scale, minor chords would correspond to the minor scale, etc.
