I have been cheery picking from "Triads and Hendrixian double stops" and as in other courses I have viewed the diminished chord is shelved. I'd like to know what are the 3 notes that make a diminished chord? What throws me off is the b7. I know a diminished chord is root, flat 3 and flat 5 but how does the flat seven enter the picture? And once the the flat 7 enters the picture then it isn't a triad any more, it's 1, b3, b5, b7 and since I want a Triad do I just eliminate the 5th or the root?
