B Diminished Cliché
I – ♯I°7 – ii – V progression in B major
B Diminished Cliché — I – ♯I°7 – ii – V
The B Diminished Cliché (B – Cdim – C#m – F#) 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 (BMaj7 – Cdim7 – C#m7 – F#7), the chromatic motion is even smoother.
