The D course rings open in the lowest shape, with the remaining notes fretted at fret 6 over a 2-fret stretch. D falls on the G course. It sounds from F#2 up to E4.
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 D 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.
