Check out these scary sounding chord progressions. Some even call it the 007 or James Bond chords. They definitely have that unsettling feel to them. I understand that they are used in Jazz however I can not think of any example of the top of my head.
For more of an idea of what is going on here, I am play Min/Maj chord. It is basically the Minor chord with a sharpened 7th. Or the Major chord with a flatted 3rd.
The first chord I am playing is FMin/Maj – F, Ab, C, and E (instead of Eb). or 1, 3b, 5, 7.
