The D Shape

The compact triangle on the top strings: root on the fourth string, the highest voice of the five shapes, and the sparkle in any chord melody.

The D shape is the open D chord — a compact triangle on the top three strings with the root on the open 4th — turned into a movable treble voicing. It is the highest-pitched of the five shapes and the one most often forgotten, which is a shame: it is the sparkle register, and chord-melody playing leans on it constantly.

Where it starts, for every root

Recomputed from the voicing library: the D shape's major form for each of the twelve roots, with its starting fret and exact frets (x = muted). The geometry is identical in every row — only the address changes.

Using it

The D shape is position 5, the last link: above every D shape the C shape reappears and the cycle restarts an octave up. Because it uses only the top strings, it excels where full chords would be mud — second-guitar parts, high fills behind a vocal, and the closing voicing of a fingerstyle arrangement.

Start from open D, then slide the triangle to fret 2 for E major (root on the 4th string, fret 2). The table above gives all twelve addresses. Played after an E-shape barre of the same chord, it adds a register jump that sounds like a second guitarist — one chord, two floors of the same building.
