Avant Garde Music
I love the music of the beginning of the last century. Schoenberg is one of my favorite composers ever. This sort of music is often called avant garde. I Like the title, why not. It means being ahead of the time.
Sure, Schoenberg was ahead of his time. If you look him up on YouTube and read the commentaries on his music. It becomes quickly clear how far ahead he was. So far that his music is still today a confrontation for people.
People tend to call it heartless and cold. I call it emotional on a technical level beyond imagination.
