Watch the I - IV - V Ionian online guitar lesson by Robbie Calvo from Modal Expose
I've chosen to play all three examples in open position to make sure the concept is clear and obvious that nothing confuses the tonality and resolution points.
The Ionian progression is pretty simple and the best way for you to get that under your fingers is to watch the breakdown in the video. You could also try working out some overdub parts for this track. An acoustic guitar part strumming through the chords would sound great.
Be sure to understand that you hear this progression resolve to the I A major.
