What is true of it

Dm7♭5 is D, F, A♭ and C — 1, b3, b5 and b7 counted from D.

These are also the notes of Fm6/D. Which name is right depends on what is underneath and what came before — the notes alone do not decide.

The easiest of the 5 fingerings below is xx0111: 3 fingers, held at the 1st fret.

1 of them use open strings, which is what makes a shape quiet to change to.

2 of the 5 need a barre.

2 strings stay silent.
