This is interesting isn't it!

So basically you are saying that when you see a dim7 chord, you really are seeing it as a diminished chord add 7, rather than a dim7th chord. Have I got it right?




I would have seen a regular diminished chord. What I should have seen was a minor7b5 chord. To be honest, all of the arrangers I've ever played for would write it as a m7b5, not as a dim7. There was a time, I'm assuming, when the naming convention dictated that it be written as a dim7, but in my experience haven't seen it written as such. Naming conventions have been and still are evolving. Example, what used to be written as a C7sus4 is now sometimes written as a Bb/C. I had a difficult time getting used to sight reading those slash chords on lead sheets. Still do, lol.

So what Mac stated in his post about the dim7 chord was indeed correct.
