Worth A Tritone Substitution

Hey! This week we covered a dominant variant called tritone substitutions.  Let's get practicing!

1) So we know that each dominant seventh chord shares its tritone with another one. Let's see that in practice: For each dominant seventh chord below, identify the tritone, then figure out which of the other dominant sevenths listed shares that tritone.

• C7
• F7
• Ab7
• F#7
• B7
• D7

2) Alright, now let's talk II-Vs! Below are four progressions: One is a regular II-V, one a chromatic II-V, and the other two are the other variants we discussed in the video. All you need to do is figure out which is which!

3) And finally, let's take a look at those augmented 6th chords. These can be a little complicated, but let's see if you got the idea. For each of the chords below, give me the notes it would contain:

• German Augmented 6th, root: Eb
• Italian Augmented 6th, root: A
• French Augmented 6th, root: F

And that's it! Hopefully you were able to follow along fine, and we'll see you next week!
