What Chord Calculator does

The Chord Calculator on Omni Calculator determines the specific notes that compose any chord by asking for a root note and chord type. Users receive a list of pitches and interval formulas (e.g., 1, 3, 5 for a major triad) that define the harmonic structure. The tool covers 14 common chord types, from basic triads to seventh and sixth chords, and presents results in both note names and interval notation. It also links to related music calculators for deeper theory study, making it a practical reference for building chords across all keys.
