Jimmy Wybles triad combinations for creating altered dominant sounds
This is my own opinion. I learned this from much analysis of Jimmy’s compositions. Theory always follows practice in this regard. I never heard Jimmy speak about these concepts in his lectures and seminars.
Jimmy’s famous triad was an augmented sus2 sound. C-D-G#
1st ex: combining his E triad with his C triad to create a D9(b5) sound. The E triad is built on the +4 of his Bb alt scale Bb C Db E F# G A Bb
2nd: ex: combining his Bb altered scale and triad with a C triad to create a D7(#5,b5)sounds.
3rd ex: combining two C triads with two notes from his C altered scale to create a Lydian dominant sound D7(#11).
4th: ex: Combining his Bb altered scale and triad with his C altered scale and triad to create an D7alt run.
Finally a little talk about the two triads from his scale and how work as b5 substitutions for each other.
