C 11 on Double Bass

C 11 spells C – D – E – F – G – A#. 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 Double Bass's EADG strings.

On the Double Bass this is a fingerboard map, not a fret chart — the marked positions are where frets would sit. Play the tones pizzicato or under the bow; with arco sustain even a two-note double stop carries like a full chord.

Start from the root, play the arpeggio until the sound of C 11 is in your ears, then loop it against the progressions in C so the tones become choices instead of charts.
