This video is from an online Jazz Guitar live stream covering ii-V-I variations. I start with your basic ii-V-I chord progression and quickly move on to more advanced harmonies. Basic knowledge about 7th chords is assumed.
A few of the chords covered
If your interests are in jazz then you will need to know all of these variations. The premise is since the V chord is a place of tension in tonal music that one can add almost anything to this chord.
In addition, I discuss how to use the knowledge of these chords in your single-note playing. Being able to see these chord tones individually all over the neck allows one to target these different colors. I highly recommend learning your arpeggios throughout the neck on all of the strings.
Harmonies and chords are just like single-note playing, you can improvise with them as well. This is why a chord chart is a bit of a farce. It doesn’t convey all of the music, it represents one possibility; in jazz, the performers don’t play the same inversion, same voicing and same alterations of the V chord each chorus through a song. Chords are not some static never changing thing, they are alive, moving depending on the impulse and musical surroundings of the moment. If the chart says to play a V, you are free to play with it to the taste and context of the song and environment.
If you train your ears well enough, you can even learn to hear a soloist play b9’s or #9’s and alter your chords spontaneously in real time. I dare say the more you expose yourself to these new sounds, the better some of them will sound. Some may even have to grow on you.
