D upper three-note sequence.

Here’s the lovely bit.

Listen once, count with the click, then play the displayed pattern. Advance a three-note cell through the D upper fragment; let its grouping cross the quarter-note pulse. Tap the indicated string/fret positions; the number keys use the currently selected chord shape. Picking direction and fretting technique are not scored. Pattern positions count from 1; 1.5 is the & of beat 1, and 1.25/1.75 are e/a. D3 (string 4, fret 0) at 1; G3 (string 3, fret 0) at 1.5; F3 (string 4, fret 3) at 2; F3 (string 4, fret 3) at 2.5; A3 (string 3, fret 2) at 3; G3 (string 3, fret 0) at 3.5; G3 (string 3, fret 0) at 4; C4 (string 2, fret 1) at 4.5; A3 (string 3, fret 2) at 5; A3 (string 3, fret 2) at 5.5; D4 (string 2, fret 3) at 6; C4 (string 2, fret 1) at 6.5. The pattern lasts 8 quarter-note beats; leave gaps silent.
