E° arpeggio & chord for gypsy jazz
The E° 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 diminished) — with note names in English (C D E) or solfège (Do Ré Mi).
The E° chord
The E° chord voicing uses those same notes (E (R), G (♭3), B♭ (♭5), C# (°7)). Switch the fretboard to Chords to see gypsy-jazz voicings for E°, or keep Arpeggio to practise the tones one at a time — same shape, two ways to hear it.
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, °7), so you always know where the root, third, fifth sit.
