The shape nearest the nut leaves the D course open and takes the rest at fret 1. A# falls on the A course. It sounds from B##1 up to A#3.
Mandocello is strung in four courses of two, so each stopped note here sounds as two — which is why the shape rings thicker than the same grip on a single-strung instrument.
Browse alternate voicings to find the one that sits best under your fingers, then compare it with the other chord types built on A# or explore the same shape in nearby keys. The diagrams list the notes in each voicing so you can connect the shape to the theory behind it.
