Watch the Pentatonic Pattern Applications online guitar lesson by Jeff McErlain from Beginner Blues-Rock Soloing
Well, here they are, the five pentatonic scale fingerings. You absolutely, unequivocally, without a doubt, no really, I'm not joking, seriously, must memorize these. No, really! It's not that hard but it does take some time. Please keep that in mind when practicing anything.
First learn what I call Fingering 1, which I assume you already know as we've been using for the past two sections. Then memorize Fingering 2, then practice going between Fingering 1 and Fingering 2. Move on to Fingering 3 and repeat the idea. If you do this, I guarantee you'll have them in no time.
