"MIKE LAIS: Hi. I'm Mike Lais and on behalf of Expert Village, this is diminished chord voicings. Okay, so we got the diminished triad down. Let's add the 7th onto it. For a diminished 7th, you're going to want the triad to be just as it is in a diminished chord where you have one, flat 3, flat 5. And then the diminished 7th is going to be a double flatted 7. So, what do I mean by that? Well, a double flat is where, let's say, if you had a B and you're going to go to a B flat, a B double flat is the same note as A, but it's just in the chord spelling if you're going to want to put it as a double flat just to keep it technically sound. As musicians, we're picky like that. Anyway, let's take a look at it. We're going to have, alright, so we're going to have our C diminished. The C diminished triad, one flat 3, flat 5, and then to add the diminished 7th, okay, the minor 7th first off is going to be the B flat, right? Right there, but if we were to have the diminished 7th, we need to have this double flatted so we're going to go all the way down to A, right there. And that makes us chord a diminished 7th. In the root position, we have one, flat 3, flat 5, double flatted 7. That is the C diminished 7th chord."
