>>>...In C, that would be C, Eb, Gb and Bb....>>>

Oh. In that case I was spelling it right the first time. Then I went to that most indisputable of all reference resources, Band-in-a-Box. I typed in "Cdim7." The screen showed "Cdim." The notes that appear in the piano part are "C-Eb-Gb-A." So I am back to not being entirely clear on the concept.

Can you clear this up?
