Keyensianism and monetarism are essentially "how money works."
Microeconomics is "how the economy works," and while there are still divergent opinions, there's stability in that divergence. Ricardo is still foundational when it comes to trade, for example.
The premise of macroeconomics is that how money works is different to that. That started with keynes, and continues through keynesianism. Monetarism literally refers to "a theory of money."
The point is that it isn't mostly just institutional and legal knowledge of existing processes of central and commercial banks. Those things regulate and affect money, but how it works is macroeconomics.
