Example5 Static Dorian triads

Larry loves chord extensions and uses them fully when improvising. One way he achieves this sense of three-dimensional completeness is to think of a scale or extended chord as a collection of three triads. D minor can be successfully extended to Dm13 (D-F-A-C-E-G-B). When you put this into alphabetical order from D you get the D Dorian mode (R-2- 4-5-6- Larry takes this a stage further by dividing the initial 13th arpeggio or chord into three three-note segments, D-F-A, A-C-E and E-G-B, giving us Dm, Am and Em triads. See if you can find these in the opening bars of this example.
