If you’ve been around software long enough, you’ve probably seen design patterns.
Reusable structures that outlive any single language.
They trace back to a book — Design Patterns — and four authors known as the Gang of Four:
– Erich Gamma
– Richard Helm
– Ralph Johnson
– John Vlissides
Recently, going deeper into tango music, I noticed something similar.
There’s also a “Big Four”:
– Troilo
– Pugliese
– D’Arienzo
– Di Sarli
Different domain — same structure.
You can explore dozens of orchestras, just like dozens of patterns.
But these four form the foundation. Every school teaches them. Everything else builds on top.
I started to see them as clusters — reference points you can map everything else against.
If you want to explore a new domain, this might be a shortcut:
→ find its “four”
→ compare them
→ learn the differences
That’s how I’m learning musicality now — as an IT guy.
