How to read this arpeggio

The chord tones are shown as pitch classes first. In the fretboard tool, square markers represent Eb root notes, while circular markers represent the remaining tones in the arpeggio.

Use the interactive fretboard to locate the Eb root notes and connect the remaining diminished chord tones across standard tuning.

This same arpeggio shape is also commonly called Eb Diminished Triad.

Chord construction and defining tones

b3Gb
b5Bbb

Eb diminished combines b3 (Gb) and b5 (Bbb). Two stacked minor thirds produce the minor third and diminished fifth that define the triad's unstable sound.

Harmonic use

Use this arpeggio over Ebdim or as a leading-tone shape that pushes toward a chord one semitone above its root.

Practice this arpeggio on guitar

  1. Play the Eb Diminished arpeggio from one Eb root to the next in at least two fretboard positions, saying each note name and interval degree aloud.
  2. Cycle through b3 (Gb) and b5 (Bbb) in three-note groups and resolve the flat fifth by a semitone in either direction.
  3. Create a tense Eb diminished line, then resolve every note by the smallest available move into a nearby major or minor triad.
