I think the concern about execution speed of

But this is exactly what "semantics" is about, or not?

Yes, music and programming languages are ultimately
phenomena of our human brains/minds. Therefore, the

Not sure whether this is the right place to discuss
computers and programming in general: But Dijkstra's
metaphor is suggesting, that while Beethoven learned
by experiment and debugging compositions, Mozart did
not have a need for reflection while writing down
music ?
The observation above sounds

In my opinion it would be important to increase the
understanding about "semantics" and "processes". And
it would be good to introduce the concepts in a
similar way as Profokiev introduces the sound of
classical music in "Peter and the Wolf". If my
suspicion is correct, functional programming would
