A new video has been published on the YouTube channel. It contains 10 exercises with chord shapes and numeral analysis about different types of variations of the jazz blues progression for jazz guitar rhythm.
If the basic sound of jazz is based on tetrad chords (aka four-note chords), it is common to extend them with other tones. These other notes form the upper structure of a chord which includes 9th, 11th and 13th. Adding extensions to chords help to get off the beaten tracks and provides some new harmonic colors to your playing (chord soloing, comping, and arrangement). This lesson provides you useful extended major 7th chord shapes to apply to your playing.
