What notes are in an A♭ major chord?

A♭ major contains three notes: A♭ (the root), C (the major third), and E♭ (the perfect fifth).

How do you play A♭ major on guitar?

The standard voicing is an E-shape barre at the 4th fret: index finger across all six strings on the 4th fret, ring finger and pinky on the 6th fret of the 5th and 4th strings, middle finger on the 5th fret of the 3rd string.

Is A♭ major the same as G♯ major?

They're enharmonic — same pitches, different spellings. G♯ major would have eight sharps (including F𝄪), so it's essentially never used. A♭ major (four flats) is the practical spelling.

What pieces are famous in A♭ major?

Chopin's "Heroic" Polonaise Op. 53, Schubert's Impromptu Op. 90 No. 4, and Brahms' Intermezzo Op. 118 No. 2 are all in A♭ major. The key has a deeply lyrical, intimate association in Romantic piano literature.

Ab major chord — notes, intervals, and practice

A♭ major is one of the warmest keys in the western tonal system and a favourite of Romantic piano composers. The chord contains A♭, C, and E♭ — a perfect-fifth frame with two flats and a natural in the middle. Chopin and Schubert wrote some of their most lyrical works in A♭, and the key shows up in jazz ballads as a tone just dark enough to feel intimate without being heavy.

Intervals

The Ab major chord stacks two thirds on the root. Each interval and its size in semitones:

Common mistakes

A♭ major's third is C natural — not C♭ or C♯. Beginners learning the key signature (four flats: B♭, E♭, A♭, D♭) sometimes apply a flat to C by mistake, which produces an A♭ minor chord (A♭–C♭–E♭) instead. On piano, the chord's topography (black-white-black) is comfortable once learned but unfamiliar at first. On guitar, A♭ major is most often played as an E-shape barre at the 4th fret.

In context

A♭ major is the I chord in A♭ major (with V = E♭, IV = D♭), the IV chord in E♭ major, the V chord in D♭ major, and the bVI chord in C minor. Brahms' Op. 118 No. 2 in A major famously modulates to A♭ major in the middle section — a half-step shift that's become a Romantic cliché for a reason. In jazz, the ii–V–I in A♭ runs B♭m7–E♭7–A♭maj7.
