This backing track is based heavily on John's Continuum style album. The track is in the key of C# minor, and you can basically use your C# minor pentatonic scale all the way through to get that John Mayer vibe!
Your best bet over this backing track is to play using the C# minor Pentatonic scales, as well as the C# minor natural scales, both of which are shown below. If you would also like to play a few arpeggios around the chord shapes, they are also outlined below. Have fun!
This track uses a combination of major and minor 7th chord shapes. These are just examples of how we would typically play those chords over this track, but you can use any shapes you like.
