E♭7♯5 arpeggio & chord for gypsy jazz
The E♭7♯5 arpeggio is built from the notes E♭ (R), G (3), B (♯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 (E♭ whole tone), with note names in English (C D E) or solfège (Do Ré Mi).

How to practise the E♭7♯5 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 sit.
