If Justin has a module on this somewhere, that would be great! I’m not sure what to call this technique but I’ve heard many players doing it while demoing gear. It’s like they’ll play a chord and then play a bunch of scale tones right afterward, leading into the next chord. I’m pretty sure Jimi Hendrix does it a lot on Little Wing, especially in the intro.
This is the video I saw last night where I got the idea. He starts doing it around the 19 minute, 39 second mark. It looks like in this case he’s playing the chord and then just hitting notes from the pentatonic scale in that position around it. The link I provided should auto play at the part I’m talking about if you click play.
