Sorry Jack, I’m having trouble following what you mean. Is there any chance you can write out the example in interval script or regular notation, and upload it? Too many variables…it depends on what strings you are playing it on. In pat.1, b7-6-b7 when played on the 2nd str is pinky-ring-pinky. When playing the b7 on the 4th str and 6 on the 5th str, it is index (on b7) and pinky stretch (to 6). Is this what you’re asking? Of course you can shift back with your index for the 6, but it might end up being sloppy at a high tempo (this is harder in the first 4-fret zone).
