G# Diminished Cliché
I – ♯I°7 – ii – V progression in G# major
G# Diminished Cliché — I – ♯I°7 – ii – V
The G# Diminished Cliché (G# – Adim – A#m – D#) uses a chromatic diminished 7th chord built on the raised first degree as a passing chord between the tonic and ii. This half-step ascent created the nostalgic, sophisticated sound of Tin Pan Alley and 1930s jazz standards. With seventh chords (G#Maj7 – Adim7 – A#m7 – D#7), the chromatic motion is even smoother.
