Meaning and Definition
A change of key in music that uses enharmonic equivalence (different notations for the same pitch) to pivot between distant keys.
A sophisticated compositional technique where a chord is reinterpreted enharmonically (e.g., G♯ becomes A♭) to facilitate a sudden, often dramatic, shift to a tonally remote key, bypassing traditional harmonic pathways.

FAQ
Frequently Asked Questions
No. All enharmonic modulations are key changes, but not all key changes are enharmonic modulations. It is a specific, advanced type of modulation.
A common example: a German augmented sixth chord (e.g., A♭-C-E♭-F♯) resolves as expected to a G chord. But if you respell the F♯ as G♭, the same notes (A♭-C-E♭-G♭) now form a dominant seventh chord, which can resolve to a D♭ major chord, creating a sudden shift to a distant key.
It became increasingly prominent in the Romantic period (19th century) as composers sought more expressive and distant harmonic relationships, and it is heavily featured in late-Romantic and early 20th-century music.
No. It is a theoretical concept based on notation and chord function. Understanding relies on music theory knowledge, not aural pitch identification.
Enharmonic modulation is usually technical / academic in register.
