Thanks Chester, yes, I understand the 4 types of triads. I don't know what the significance of the 7th is but I understand that when a 7th is added. I know that that 7th can be added to the 4 types of triad and in 3 different flavors, minor, major, diminished. I suppose you can't have an augmented 7th because it would just give you your tonic. I'm learning this from another site as I am writing this, this one is pure theory, does not use guitar chord names. And so, here I see that each of the 3 7th, when combined with the 4 different triad types, have specific names, for example, the minor 7 goes with the minor triad and, as Deniz said, a diminished 7 can only go with a diminished triad. So for my Am7b5, it's still figuring out what the m applies to that confuses me. The 5th is flat, the m applies to the A or to the 7 or both? Since the 5th is flat that means the 3rd is flat too, so I figure the m applies to the 7. But I ask, if the 7 is minor by default and a flat 5 means a diminished chord. Why not just right Adim7? Or is this wrong?
