What to notice

Two chord tones use black keys, but the third C is natural. Do not lower C merely because the root name contains a flat. The accidental belongs to its written note unless another notation instruction says otherwise. From A-flat, C is four semitones higher and E-flat is seven. A-flat major is not A major with only its root lowered: moving the entire A–C♯–E shape down a semitone gives A♭–C–E♭.

Compare three positions

Read each bass note before selecting a position. The root-position example starts with A♭; first inversion starts with C; second inversion starts with E♭. The chord tones stay the same. These are independently chosen reference registers, not an ascending exercise. Switching a position must update the selected note order, diagram, sound and current-print snapshot together. Hand numbers, when available, apply only to the root example.

Chord reference

Common names: Ab, A-flat major, Abmaj.

Intervals from the root: perfect unison, major third, perfect fifth.

Find the notes on your keyboard

  1. Locate A-flat on the black key between G and A.
  2. Add C and E-flat, preserving each written name.
  3. The root example is A♭4–C5–E♭5. Other inversions on this page use a lower register; their bass labels tell you which chord member is lowest.

A-flat major versus A major

Compare A♭4–C5–E♭5 with A4–C♯5–E5. All three sounding pitches move up one semitone to make A major; simply changing A-flat to A would not give the same result.

G-sharp major is enharmonically related but spelled G♯–B♯–D♯. This page keeps A♭–C–E♭ because it answers the A-flat query, not a separate G-sharp spelling lesson.

Connect A-flat major with C minor

A♭–C–E♭ and C–E♭–G have two shared tones, C and E-flat. Shared tones can make a comparison easier to follow without making the chord names interchangeable.

Use C4–E♭4–A♭4, then C4–E♭4–G4. The first is A♭/C; the second is Cm. Only the highest written note changes in this example. No transition fingering has been assigned.

Name the three chord tones before looking back at the answer. Then name the bass of the first inversion. These are written self-checks, not additional scored modes.

  1. Chord-tone answer: A♭, C, E♭.
  2. First-inversion bass: C. The root is still A♭.
