Thanks! I will take a look at that website.
But I think I first have to read about the Roman numeral system, because I didn't learn it.
I think I can describe myself as a lazy beginner who can play intermediate pieces. Or an intermediate amateur who skipped some important things.
I can hear the difference between major and minor and I can play all major and minor keys, but I don't know how I learned it. I never practice scales or arpeggios, I want to, but I'm always going to start next week. I don't know a lot about theory, chords and so on. I can play or sing a melody back. I didn't understand it at first by the way, because my English is not so good. I thought he meant that you had to play the melody backwards. I thought, oh my god, do you have to be able to do that??
