Csus2, also called C suspended second, contains C, D and G. Use the piano diagram to find the notes, hear the chord and explore its inversions.
The c suspended 2nd chord replaces the third with a major second.
Preserve the written note spelling shown for this chord.
Choose a position to keep the written notes, sounding keys, bass note, playback and print reference synchronized.
Csus2 uses 1–2–5: C–D–G.
Compared with C major, replace the third with the second.
The chord tones stay the same while the lowest chord tone changes.
