I wasn't introduced to programming through BASIC so I can't speak to your analogy, but I believe you've taken me to say "hiding complexity is wrong." I don't think any point that I've made can be interpreted this way. There's plenty of low hanging fruit for beginner music theorists. "V7 resolves to I" is low hanging fruit, and it has tons of underlying complexity that you don't need to understand as a beginner. It's understood by every educated musician. My point is that if you want to be understood by other musicians you should learn this:

  V7 -> I 

and not this:

  (x+2, x+5, x+7, x+11) -> (x, x+4, x+7, x+12)
