B7♯5 arpeggio for gypsy jazz
The B7♯5 arpeggio is built from the notes B (R), E♭ (3), G (♭6), A (♭7). On Haute Gitanerie you can see it across the whole guitar neck — contained position boxes, long diagonal forms, and its parent scale (B whole tone) — with note names in English (C D E) or solfège (Do Ré Mi).
How to practise the B7♯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, ♭6, ♭7), so you always know where the root, third, fifth and seventh sit.
