Here is a practice track for beginning and intermediate guitarists – done in a light rock style. The chords are
||: G |Am |D7 |G : ||
Practice soloing over the progression using the G major scale. Some other strategies you might find interesting to play with are
- Use the arpeggios for G major seventh, A minor seventh, and D seventh over the appropriate chords
- Use G major (E minor) pentatonic or D major (B minor) pentatonic over the G major chord, and A minor pentatonic over the A minor and D7 chords. Note that all three of these pentatonic scales contain only notes from the G major scale.
- Mix up arpeggios, pentatonic patterns, and major scale runs.
Enjoy!
