Song Science #4: Mastering Modulation in your Songwriting

Demonstrates parallel key modulation between major and minor keys, using the dominant five chord to shift into a parallel major bridge and back to minor verses, for brighter contrast.

Explore how to blend relative key modulation with parallel key modulation using a deceptive cadence, illustrated by St. Elmo's Fire moving from A to F sharp major for chorus.

Learn direct (abrupt) modulation, a key change that happens without preparation or telegraphing. See a chorus example moving from D to Eb to observe how melody and chords shift together.

Demonstrate how pivot chords enable smooth modulation between keys by sharing chords like F minor between C minor and A-flat major, creating a lift with the five and four chords.

Explore modulation distance using the circle of fifths, noting near keys with pivot chords and far keys—tri-tone away—driving half-step direct modulations or truckdriver modulations.

Learn common tone modulation with pivot notes to shift keys, via sustained notes with changing chords or immediate pivots, illustrated by all by myself and total eclipse of the heart.

Learn to modulate with altered pivot chords, using a flat-seven borrowed chord in D that becomes the five in F, and leverage modal interchange and secondary dominants.

Learn chromatic mediant modulation and how it contrasts with diatonic mediants, using common and altered tones to move between keys, illustrated with Hero by Mariah Carey.

Explore upward modulation in songwriting by using a pivot five chord to modulate up a whole step, and employ abrupt half step shifts with minimal telegraphing.

Learn downward modulation with Penny Lane's shift from B to A, using pivot chords and common-tone pivots to keep energy through an upward melody.

Modulating from any key to nearby or distant keys, including parallel, relative, and relative parallel options. Start applying this by writing songs with parallel minor or relative minor modulations.
