DmΔ arpeggio for gypsy jazz
The DmΔ arpeggio is built from the notes D (R), F (♭3), A (5), C# (7). On Haute Gitanerie you can see it across the whole guitar neck — contained position boxes, long diagonal forms, and its parent scale (D melodic minor) — with note names in English (C D E) or solfège (Do Ré Mi).
How to practise the DmΔ arpeggio
Start with a contained position box near the low strings, then move it up the neck fret by fret, or follow a diagonal form for a two-octave sweep in the manouche style. Every note is labelled with its interval (R, ♭3, 5, 7), so you always know where the root, third, fifth and seventh sit.
