F 13b9 on Bass VI

Root first, then the colors: every F 13b9 tone placed on the EADGBE neck, ready to walk.

F 13b9 spells F – F# – A – C – D – 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 VI's EADGBE strings.

The Bass VI is tuned EADGBE one octave below guitar, so six-string grips physically fit — but at this depth stacked thirds blur, and the voicings that stay clear keep two or three notes and let the low strings breathe.

Start from the root, play the arpeggio until the sound of F 13b9 is in your ears, then loop it against the progressions in F so the tones become choices instead of charts.
