Answer:
Semantics.
Explanation:
Semantics cares about the meaning of a word or a sentence. In this case, Altman is equating a genre's visual conventions with sentence's semantics. The effect might be the same: To use different combinations of words or drawings to achieve the desired effect. As Altman says: just as we know that some words don't logically work together, we also sense that a menacing castle doesn't fit in the Western. The example he uses means to find meaning in something that should not be there.
A lot of pop music producers will start with a basic four-chord pattern, I–V–vi–IV. For example, if you are in the key of C Major, you would play a C Major chord (CEG), a G Major chord (GBD), a A minor chord (ACE), and an F Major chord (FAC). That is a popular "template" so to speak that can lay down the basic line for you to put other instruments over.
If you really want to get involved, a little bit of music theory never hurt anybody. You don't need to know much to get a basic understanding of the way things work.
I hope this helps :)
