E 7#9 on Bass (4-String)

Root first, then the colors: every E 7#9 tone placed on the EADG neck, ready to walk.

E 7#9 chord diagram, starting at fret 1. Strings low to high: E open, A 11th fret, D open, G open.

E 7#9 spells E – G – G# – B – D. A bassline treats those notes as a hierarchy — root first for gravity, fifth for stability, then the third and any extensions for color — and the shapes below put each of them under your fingers on the Bass (4-String)'s EADG strings.

Full chords are optional equipment on bass: down low, stacked thirds turn to mud, so the grips that work keep two or three notes — root-fifth, root-tenth, shell voicings — and the arpeggio is how the rest of the chord becomes a line.

Start from the root, play the arpeggio until the sound of E 7#9 is in your ears, then loop it against the progressions in E so the tones become choices instead of charts.
