How to read this arpeggio
The chord tones are shown as pitch classes first. In the fretboard tool, square markers represent C root notes, while circular markers represent the remaining tones in the arpeggio.
Use the interactive fretboard to locate the C root notes and connect the remaining minor add9 chord tones across standard tuning.
This same arpeggio shape is also commonly called C Minor Add 9 or Cmadd9 or C min add9.
Chord construction and defining tones
C minor add9 is defined by b3 (Eb) and 9 (D). It keeps the minor triad and adds the ninth without adding a seventh.
Harmonic use
Use this arpeggio over Cmadd9 and minor chords where the natural ninth is part of the voicing or melody.
Practice this arpeggio on guitar
- Play the C Minor Add9 arpeggio from one C root to the next in at least two fretboard positions, saying each note name and interval degree aloud.
- Connect b3 (Eb) and 9 (D) across two octaves and compare the color of the ninth against the minor third.
- Play over Cmadd9, treating the ninth as a color tone that resolves to the root or minor third.
