A# m(maj11) on Bass (4-String)

A# m(maj11) spells A# – C – C# – D# – F – 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 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 A# m(maj11) is in your ears, then loop it against the progressions in A# so the tones become choices instead of charts.
