To play a major seventh, we play the seventh degree of the scale plus one half step. I've never really understood why it's called a *major* seventh, so maybe this can be cleared up for me here. My main question, however, is whether or not this addition can be applied to a minor chord. That is, if I had a D minor, and I wanted to add the seventh note plus one half step, my notes would include D, F, A, and C#. Is this traditional?
