What chords is he talking about (or did he mis-type)? I read "5-chord with flat-7" as G7 and "flat-2" as Dm7, but G7 and Dm7 don't share a tri-tone, only an interval. ?
- zodiac 4y agoThe chord is D-flat dominant 7 It’s the same example as on the wiki page for “tritone substitution” - ‘For example, in the key of C major one can use D♭7 instead of G7.’
