Does anyone know about these in and out? Because I need help. I'm confused about the process of identifying the types. For our homework, my teacher wants us to notate them in this format: M (or m depending on whether the triad is major or minor) followed immediately by M (or m depending on whether the 7th is major or minor)

So for example:

We have G as the root, B as the third, and D as the fifth, and F as the seventh, so it would identified as "Mm7" because the triad is Major and the seventh is minor.

Here's the confusing part: do I identify it in the way I mentioned above or do I identify the chord as a dominant seventh chord since the triad is major and the seventh is minor?
