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 – G#dim – Am – 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 (GMaj7 – G#dim7 – Am7 – D7), the chromatic motion is even smoother.
