Play only the root on the first beat of each change: B (bar 1, Bmaj7), G# (bar 2, G#m7), E (bar 3, Emaj7), F# (bar 4, F#7), B (bar 5, Bmaj7), G# (bar 6, G#m7), E (bar 7, Emaj7), F# (bar 8, F#7). Keep counting through every bar that holds the same chord; the form resolves back to B.
When each chord arrives, land on its third and hold it for a beat: D# over Bmaj7, B over G#m7, G# over Emaj7, A# over F#7. Then repeat with the seventh (see the table) to hear how the line leads into the next chord.
Play B Mixolydian (B C# D# E F# G# A) up and down in frets 6–10, one note per beat at 126 BPM. Start and finish on B: 6th string fret 7, or 5th string fret 2 for the next position up.
