Free Ear Training: Identify Chords & Progressions by Ear

Learning to identify chords by ear transforms how you play, write, and transcribe music. Rather than memorizing songs chord-by-chord, developing relative pitch allows you to recognize harmonic movement in real time regardless of the musical key.

What Roman Numerals Mean in Ear Training

In functional music theory, Roman numerals describe scale degrees and chord qualities relative to the tonic key. Uppercase numerals (I, IV, V) indicate major chords, while lowercase numerals (ii, iii, vi) signify minor chords. Hearing harmony through numbers rather than fixed letters enables you to recognize recurring song cadences across all 12 keys effortlessly.

Why Relative Pitch Matters

You do not need absolute pitch to excel at music. Relative pitch teaches your ears to perceive the emotional tension and resolution between harmonic degrees: the grounding stability of the tonic (I), the expansive lift of the subdominant (IV), the driving pull of dominant tension (V), and the melancholic depth of the relative minor (vi).

Common Progressions to Learn First

• I–IV–V–I: The foundational classical and blues resolution from home to departure, tension, and release.
• vi–IV–I–V: The emotional modern pop and ballad progression that starts with reflective minor color.
• I–vi–IV–V: The nostalgic 1950s doo-wop progression that underpins hundreds of timeless radio hits.
