What It Is
A dominant seventh chord plus a raised (sharp) ninth above the root - often called the 'Hendrix chord'. Notes: C, E, G, Bb, D#.
How It Functions
Combines a major third with a blues-inflected, minor-third-sounding sharp ninth (the same pitch class, spelled differently) for a gritty, dissonant dominant color.
