You learn these things outside of school. You learn very little that is important at school, actually.
We do learn music here at school. I do even know personally a few people from my own school time who had music as one of their Abitur subjects.
The greatest part, however, of learning music is being taught in both public and private "Music Schools".
The basics of music (and easy instruments) are taught at school, but learning real instruments usually takes place in those music schools. That's how I had learned the guitar, too.
