A#m6/9 arpeggio for gypsy jazz
The A#m6/9 arpeggio is built from the notes A# (R), C (2), C# (♭3), F (5), G (6). On Haute Gitanerie you can see it across the whole guitar neck — contained position boxes, long diagonal forms, and its parent scale (A# Dorian) — with note names in English (C D E) or solfège (Do Ré Mi), and audio playback.
How to practise the A#m6/9 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, 2, ♭3, 5, 6), so you always know where the root, third, fifth and seventh sit.
