- Brief character
- Softly tense sound — the main chord of minor jazz cadences. Unlike dim7, the minor (not diminished) seventh makes the sound softer and less symmetric.
Softly anxious, "smoky", jazzy. Yearning, irresolution, introspection.
Recognized by its softly anxious sound — softer than dim7, darker than m7.
Notes & degrees
Diminished triad + minor seventh: 1-b3-b5-b7.
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
From dim7: b7 instead of bb7. From m7: b5 instead of 5.
