The Ddim chord
Hear the Ddim and you hear the ragtime piano grease, courtesy of the diminished triad spelling (D - F - G#). Players use it to create a moment of doubt, which is why it turns up across early jazz and the Great American Songbook. Common voicings on guitar and piano, the theory in plain language, the progressions where the chord earns its place, and a list of real song references are all in the sections that follow.
