Precede any chord (major or minor) with a dominant 7 chord a 5th above. E.g. if you have a C minor chord coming up, you could add a G dominant 7 (G B D F) just before the C minor chord.2. Go one step further, and apply tritone substitution to that added dominant 7 chord. The basic concept of tritone substitution is this: every time you see a dominant 7 chord, play the dominant 7 chord a tritone away instead (up or down). In the C minor example, instead of playing G dominant 7, we would play a Db dominant 7 chord (Db F Ab Cb) because Db is a tritone away from G. Db dominant 7 will resolve nicely to C minor, and will create an even more sophisticated sound. (See my video on tritone substitution - just search 'tritone substitution' in youtube). 3. And lastly, I use side-slipping to embellish the basic chord progression. Side-slipping is where you move every note of your chord voicing in parallel, up or down by the same distance. Moving up/down in half-steps or whole-steps is particularly effective, and is often a good way to add a passing chord between 2 chords in the chord sheet.Every time I add a new chord to the chord sheet (aka 'reharmonization') I try to choose chords which imply a new scale to the previous chord. This is generally what gives jazz an interesting and sophisticated sound - it's constant shifting of scale / harmony.I also share my thoughts on performing chords - my main focus when playing chords is playing every note at the exact same time. And I also encourage you to try playing quietly when you have a nice and sophisticated chord progression like this one.I make all of my tutorial videos for free, but have to charge for some items to fund the making of future videos.Thank you for watching.Please 'LIKE', COMMENT & SUBSCRIBE, and let me know what you think of this longer video length.
