As with intervals and single line solo playing, you can use the inner logic of the mixolydian scales when you’re using chord riffs.
Chords are made from scales and when you move from chord to chord, the notes you can use in solos and accompaniment move with the chords.
The next example deals with this inner logic.
The pattern you find in bars 1-4 can easily be moved up to the 7th and 9th fret when you move to the IV chord C and to the V chord D.
But why walk a marathon, when you could stroll around the corner?
By changing just 1 note, the same riff can be applied to the IV chord.
Move this IV chord pattern up 2 frets and you’ve got your V chord riff.
If you use this riff in a medium tempo song, play only downstrokes, except when playing triplets. Use up and down strokes when the tempo is too fast or when you’re playing those triplets.
When you play this way, the groove sounds fresh and upbeat.
The audio example uses the inner logic and stays in position (2nd chorus).
