Watch the The Roadmap: Major Pentatonic online guitar lesson by Robbie Calvo from Power Play: Dominant
Each chord progression example presented in this Power Play Dominant course consists of one chord progression that has been transposed into 4 different keys. Each key lasts for the duration of 8 bars. In this first example you are going to be playing over these 4 keys in sequence - G7 - Bb7 - Db7 - E7. This sequence of key changes will repeat 4 times. Don't think that's long enough? Well, this sequence played 4 times will be approximately 6 minutes. That's 6 minutes of intensely focused solo creation in 4 different keys 4 times over, that's a lot of work! Check out the chord chart to see what is actually happening in the harmony. It's not necessary to learn the chord progression but if you are curious go ahead, it's a nice little vamp you can jam with your friends.
