Learning Major second chords.. Help!

[jontah]

Hi!

I'm learning Major second chords at the moment, and I'm following some awsome tutorials from a guy called Terrence (Quaverbox).

But in his Major 2nd chords section where he is teaching us major 2nd chords, he says "lets move on - A minor 7", thus he is playing a D and B and not a E and B for instance. I really don't understand this. Can someone help me understand what he is playing?

I don't think he does this by mistake since he's doing it several times during the video even in other chapters.

Here's a short snippet from the movie (he plays this at 0.21 seconds in this clip down here):

Please help so I can move along with my practice.

Cheers.

Best,
