According to Frank, a brilliant Aussie guitarist you can use pentatonic shapes in moral playing, the example would be D dorian, parent is the key of C, you can use first position pentatonic shapes on D/E/A. The source is in Frank Gambale technique book one
Hi Lee
Thanks for your quick response to the Frank Gambale point, you can find a free pdf of the book I’m talking about. I tried to unload a picture but did not have permission. So I will write out what he said on page 20 of the book.
Scale: G dorian=2nd more of Fmaj= 12b3456b7 for G=GABbCDEF. Pentatonic Dm=DFGAC. His formula goes
Scale Dorian=pentatonic/blues up a fifth, arpeggio maj7 up/min 3rd. Triad maj down whole step. As I said above the book is called the Frank Gambale technique book one I bought it years ago in OZ, but it’s free on the internet as a pdf, I use it mainly in an Ionian context using eminor petatonic.
