A seventh chord with a flat 5th is simply what it says — a dominant 7th chord with the 5th scale note lowered 1/2 step. The symbol for a C7 with a flat 5th would be C7-5. The symbol for an F7 chord with a flat 5th would be F7-5.

Augmented 7th chords are formed by combining an augmented triad with a lowered 7th of the major scale of that particular key.
Minor chords with a major 7th added are not used a great deal, but musicians really need to know all possible chords and combinations. These are created using a minor triad with the 7th degree of the major scale added.
