Dark, tense, "constricting". Drama, anxiety, cinematic tension.
Defined by the dense, compressed sound of three consecutive minor thirds.
Notes & degrees

On the piano
An arpeggio is a broken chord: the same notes played one after another rather than together, bottom-up and back. On the piano they are usually split between the two hands — in an accompaniment, for instance, the left hand carries the bass while the right fills in the figuration.
Any chord can be played arpeggiato or turned into figuration — a broken bass, Alberti figures, a waltz accompaniment. Unlike the guitar, where an arpeggio is tied to the order the strings are plucked, there is no fixed fingering “shape” here — evenness and legato between the notes matter most.
Chord basis
Differs from m7b5 by having a diminished (not minor) seventh.
