The Amaj7 chord contains A, C♯, E and G♯: an A major triad with a major seventh. Find all four notes on the piano, then compare root position and inversions.
Build the Amaj7 chord with degrees 1–3–5–7. The G♯ is eleven semitones above A; changing it to G gives A7 instead. Keep the seventh visible when comparing the two sounds.
Preserve the written chord spelling shown here; keyboard equivalence does not rename the chord.
Choose a position to keep the four written notes, sounding keys, bass note, playback and print reference synchronized.
To check the Amaj7 chord, select A, C♯, E and G♯ in the note exercise. The exercise checks your selection on this page; it does not listen to your piano.
Amaj7 uses 1–3–5–7: A–C♯–E–G♯.
Amaj7 is a major triad plus a major seventh.
Compared with A major, add the major seventh above the root.
A seventh chord has four chord tones and therefore four positions: root position plus three inversions. The slash symbol identifies the written bass note.
| Position | Symbol | Notes, low to high | Bass |
|---|---|---|---|
| Root position, current selection | Amaj7 | A3–C♯4–E4–G♯4 | A3 |
| First inversion | Amaj7/C♯ | C♯4–E4–G♯4–A4 | C♯4 |
| Second inversion | Amaj7/E | E4–G♯4–A4–C♯5 | E4 |
| Third inversion | Amaj7/G♯ | G♯4–A4–C♯5–E5 | G♯4 |
An Amaj7 chord inversion rearranges the same four notes. Finger numbers are not prescribed here; use the displayed keyboard to identify the notes before choosing a comfortable hand position.
Use the written notes, keyboard positions and playback without treating the diagram as a required hand shape.

A, C♯, E and G♯. The formula is 1–3–5–7: root, major third, perfect fifth and major seventh.
No. A7 uses G natural, while the Amaj7 chord uses G♯. The other three notes, A–C♯–E, stay the same.
Move the lowest note up an octave while keeping all four chord tones. The first inversion has C♯ as its lowest note. Select each position to compare the keyboard and sound.
No. The diagrams identify keys and note order. They do not prescribe fingers or assess your hand movement.
Select the four pitch classes that make Amaj7, then check your answer.
This one-octave exercise checks the exact four-note pitch-class set. Order and inversion do not affect the result; missing and extra notes are reported, while fingering and live performance are not assessed.
One octave, C through B. Select a key again to remove it.
