Watch the D Mixolydian Soloing online guitar lesson by Robbie Calvo from The Modal Alchemist
This solo reminds me of 80's rock in the vein of Bryan Adams. I love Keith Scott's playing from that band. He hits all the right tones at all the right times in my opinion he's a sweet notes kind of guy!
My main objective is to make a musical statement when playing a solo so I try to listen to the underlying harmony to get suggestions and clues for my phrasing. I sometimes hear the parts or phrasing in my head and then I try to locate that or replicate the idea on the fretboard. Most of the lines I played are pretty simple but I think they worked within the context of the music. Nothing flashy, just musical if at all possible.
You'll notice that I play a couple of D9 arpeggio ideas even though our V chord is major not dominant. This implies the mixolydian sound even more but adding the characteristic note, C. You'd swear the chord changed to a D7, but it doesn't. Very cool sound indeed.
