Diminished 7th chord

[Fred McCoy]

Brian, first and foremost: I found your website serendipitoulsy and what a find! I’m at a point in my playing where your lessons are tying all of the disjointed “stuff” I’ve learned together. Thanks so much.

In lesson EP378 you call out a chord as a diminished A#7th and imply that the open “e” makes the A#dim a 7th chord. I don’t understand that, the ‘e’ you are already playing as the b5. I thought the diminished chord was a 1, b3, b5, bb7. In this case I think the bb7 would be a G. I’m not confident about my theory so could you explain?

I know that you have to call out fret-board notes as tab because many people don’t know the names of the notes. Could you also say the name of the note? For example “The ‘a’, second string, 10th fret”

Thanks again!

Hey Fred,
I’m working with this same lesson. I think you are correct that the top note in a A# dim 7 chord would be the G. That would also create the ‘usual’ fingering for that chord, adding the G, first string, third fret. In context of the lesson, it seems Brian omits the G, which is fine because it fits the melody. I don’t think he plays the E on top. Technically, you could call that A#dim, leaving off the 7.

So, your theory is right on, as far as I see.

Best,
Michael

I think Brian got confused with the other A#dim, later in the piece, which has the bb7 but no b3. So you are absolutely correct, Fred.

I just printed out the score and Brian has it correct there.
