Play only the root on the first beat of each change: D (bar 1, Dmaj7), B (bar 2, Bm7), G (bar 3, Gmaj7), A (bar 4, A7), D (bar 5, Dmaj7), B (bar 6, Bm7), G (bar 7, Gmaj7), A (bar 8, A7). Keep counting through every bar that holds the same chord; the form resolves back to D.
When each chord arrives, land on its third and hold it for a beat: F# over Dmaj7, D over Bm7, B over Gmaj7, C# over A7. Then repeat with the seventh (see the table) to hear how the line leads into the next chord.
Play D Mixolydian (D E F# G A B C) up and down in frets 9–13, one note per beat at 126 BPM. Start and finish on D: 6th string fret 10, or 5th string fret 5 for the next position up.
