Music Theory: Tri-Tone (Flat-Five) Substitution

http://www.creativeguitarstudio.com/

Andrew Wasson of Creative Guitar Studio presents a guitar lesson in Fingerstyle Guitar...

Q: Hi Andrew, what is the difference between Tri-Tone Substitution and Flat-Five Substitution? They kind of seem like the same thing to me... I have read a few lessons on the net about this stuff, but I am still a little unclear on what's up with this theory concept. Could you do a video about this?
Thank you -- Xavier in Sydney


Thanks for writing in Xavier... Ya know this is one of those theory topics that has more than one name. Tri-Tone Substitution, Flat-Five Substitution, Substitute Dominants, Sub-Five chords... it's enough to drive you crazy -- but they all are indeed the same thing.
What this deals with is a chord substitution where a Dominant 7th chord gets replaced by another Dominant 7th chord a diminished 5th interval away.

The complete lesson article for this video will be available on the Creative Guitar Studio website shortly. Follow me on Twitter for lesson posting announcements:

Actually, I am not a guitarist at all, haha. I'm just good at scales and chords and stuff.
