The Piano Chord Collection — Suspended 2nd & 4th
PianoChord.org
Supports: sus2 chord formula and written tone pattern
Scope: Supports the chord formula and spelling only; keyboard layouts are PianoGrid examples, and no fingering is assigned.
The Gsus2 chord contains G, A and D. Its formula is 1–2–5: A replaces the third of G major. Locate the three notes, then compare root position with two inversions.
Build the Gsus2 chord by keeping G and D from G major and replacing B with A. The second G–A spans two semitones, while the fifth G–D spans seven. Neither B nor B♭ belongs to this suspended collection.
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.
Build the Gsus2 chord by selecting G, A and D in the exercise. Adding B gives the four pitch classes of Gadd9, rather than the three requested here. This check does not assess hand shape, rhythm or live playing.
Gsus2 uses 1–2–5: G–A–D.
Compared with G major, replace the third with the second.
The chord tones stay the same while the lowest chord tone changes.
| Position | Symbol | Notes, low to high | Bass |
|---|---|---|---|
| Root position, current selection | Gsus2 | G3–A3–D4 | G3 |
| First inversion | Gsus2/A | A3–D4–G4 | A3 |
| Second inversion | Gsus2/D | D4–G4–A4 | D4 |
Select a Gsus2 chord position to compare its lowest note. All three positions preserve G, A and D. The diagrams identify keys and registers rather than prescribed fingers; follow the written low-to-high order when reading a new position.
Use the written notes, keyboard positions and playback without treating the diagram as a required hand shape.

G, A and D: root, major second and perfect fifth. The formula is 1–2–5, without a third.
No. The Gsus2 chord omits B, the third. The complete Gadd9 collection includes G, B, D and A. Compare the note lists rather than assuming that 2 and 9 make every symbol equivalent.
The Gsus2 chord uses A, the second above G. Gsus4 uses C, the fourth. Both keep G and D while omitting the third.
A starts the first inversion and D the second; root position starts on G. Each displayed position keeps all three chord tones and changes their order.
Select the three pitch classes that make Gsus2, then check your answer.
This one-octave exercise checks pitch classes. Order and octave do not affect the result; fingering and live performance are not assessed.
One octave, C through B. Select a key again to remove it.
