A working voicing
Split the chord between two hands the way working players do — a solid shell low down, the colour tones up top:
| Hand | Keys |
|---|---|
| Left (shell) | G♭2 – D♭3 |
| Right (colour) | B4 – D♭5 |
Where F♯sus4 lives
Suspend and resolve
F♯sus4 → G♭
The suspension releases into the plain triad — tension, then home.
As a pad colour
G♭sus → E → B
Kept unresolved, the sus chord floats — a staple of modern pads.
