D# 6sus4 — Lap Steel
D# 6sus4 has no bar or slant position in the lap steel's C6 tuning.
D# 6sus4 stacks D# – G# – A# – B#, and no bar position on the lap steel's six strings in C6 sounds that set: at every fret, and on every short slant, a tone it needs is missing or too few strings carry it.
A fretted instrument would reach for a grip here. A steel has no fretting hand, so this page charts nothing rather than a shape no bar can hold — the qualities this tuning does spell are on the chord list for this root.
