Define diatonic harmony and give one short worked example.

# Diatonic Harmony **Definition:** Diatonic harmony is a system of harmony that uses only the seven notes of a major or minor scale, without chromatic alterations. Chords are built from these scale degrees, and harmonic progressions move between them. ## Short Worked Example **In C Major:** The diatonic scale notes are: C - D - E - F - G - A - B The seven diatonic triads built on each scale degree are: - **I: C major** (C-E-G) - **ii: D minor** (D-F-A) - **iii: E minor** (E-G-B) - **IV: F major** (F-A-C) - **V: G major** (G-B-D) - **vi: A minor** (A-C-E) - **vii°: B diminished** (B-D-F) **Sample progression:** I - IV - V - I - C major → F major → G major → C major This is purely diatonic because all chords use only the seven notes from the C major scale.
