Watch the Blues: Technique 12 online guitar lesson by Robbie Calvo from RhythmCraft
In this example I wanted to show you another example of how to layer up parts on this 12 bar blues progression.
My first guitar part is using the acoustic guitar to play the boogie rhythm patterns I showed you. This works really well on the acoustic guitar because it gives us some really nice percussive sounds as well as a rocking rhythm.
Now I need to choose an electric guitar part that isn't as "busy' as my acoustic part. I'm hearing the major sixths approach this time and you can hear that it works really well. This guitar part leaves space in the arrangement, gives me a harmonic variation to my first part and it's also being played in a different frequency range on the instrument.
My third guitar part is the walking bass line approach and I've chosen this single note part because we already have two other guitars playing the chords. I think you'll agree that it's a very sensible choice because it solidifies the bass line and the chord changes without stepping on the toes of the other guitar parts.
If in doubt of what parts to choose, just sit back and listen for a minute and try to hear in your mind's ear what the best approach would be. If it doesn't need anything, don't play anything until it does!
