The tab examples below show the scales used for soloing. You can play G minor pentatonic over all of track 5. However, you can lock into the chord progression even better by changing to C and D minor pentatonic as well. The score above suggests when you should change scales.
Start by confining your solos to the second, third, and fourth strings. Soloing here looks and feels a lot like standard tuning.
This is why we started with open G, because open G has three strings tuned the same as standard tuning. It makes it easier for guitarists new to alternate tunings to learn how to solo over open tunings. When you can solo over these three strings, expand you playing to the rest of the strings.
The last track contains just the rhythm guitar part, so you can practice soloing over it. Here is your chance to play like the rock stars with the open G tuning. If you solo using a slide, you have the flexibility to lock the tuning of the solo in with the rhythm guitar’s intonation.
