C#7 arpeggio & chord for gypsy jazz

The C#7 arpeggio is built from the notes C# (R), F (3), A♭ (5), B (♭7). On Haute Gitanerie you can see it across the whole guitar neck — contained position boxes, long diagonal forms, and its parent scale (C# Phrygian dominant) — with note names in English (C D E) or solfège (Do Ré Mi).

How to practise the C#7 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.

Manouche alternatives

On a dominant, the ♭9 — or the diminished a semitone above (the 7♭9 without its root) — adds the manouche tension.
