Ionian ♯5 (augmented) scale in C on electric guitar
Ionian ♯5 (augmented) scale in C: C, D, E, F, G#, A and B, the degrees 1–2–3–4–#5–6–7. The box shown is in open position, from the open strings up to fret 4; the lowest tonic sits on the 5th string, fret 3, and the hand stays put in the region, with no position shift.
On electric guitar, the slimmer neck invites legato — the same fingering runs with less effort, and the high positions stay comfortable. Plugged into an amp, each chord sustains for as long as you hold it, and the tone — clean or driven — shapes the whole sound.
Once the shape is memorized, play the box in thirds: the real memory test.
