Sorry…a bit rushed. Should have been F# ( unless you want to play in the minor ). Also, I guess I should have used ” root note ” as you drop back to the starting note….NOT…DF#GA….D2….but back to D1. Then the same prog in E flat….E….etc.
Its a great tension builder. You can simplify it by playing root-5-root…same priciple. Stick with one note whichever pattern you choose. Get used to picking up speed and hitting the notes. To be honest, I don’t often use it in solos. A jam…yeah, but its a pretty intense exercise, if you mess it up….oh man !!
