This guitar lesson discusses a very useful way to come out new colors to your soloing or comping ideas called "Upper-structure Triads. This technique consists of superimposing triads to highlight extended notes of minor, major and dominant chords.
When learning how to play jazz guitar, one of the most important device to master is to play each tone of a chord in order to outline a specific progression.
This is what we call arpeggios. They are great melodic tools when you want to highlight the chords you are soloing over.
This lesson is focused on diatonic seventh arpeggios and their extensions. In a first time, before applying these extensions, it is recommended to have a very strong knowledge of the triads, both the chords and the arpeggios.
