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