E♭ major has three flats — B♭, E♭, and A♭ — and is a warm, full-bodied key especially popular in jazz, swing, and classical works featuring brass. Mozart's Symphony No. 39, Beethoven's "Eroica" Symphony, and most big-band charts use E♭ as a home key. It sits three counter-clockwise steps from C on the circle of fifths.

Common progressions

In E♭, I–V–vi–IV is E♭–B♭–Cm–A♭. The ii–V–I jazz cadence is Fm–B♭–E♭, ubiquitous in standards. Many famous ballads and jazz heads ("Misty," "Body and Soul") are in E♭ or B♭, partly because the key suits horns.

Relative minor

The relative minor of Eb major is C minor — it shares the same key signature, just centred on the 6th degree of the Eb major scale (C). A piece can move between Eb major and C minor freely without any change of accidentals.

Common mistakes

The three flats are added in order: B♭, E♭, A♭. A common mistake is forgetting the A♭ — the 4th degree is flat, not natural. Pianists sometimes hesitate on E♭ chords because the topography (mostly black keys with one white) is less familiar than C's all-white chords.
