"I love this course! Gjermund is a great instructor and thanks to his lessons my playing has improved greatly. This course has taught me much about the music form and I have come into a greater appreciation of piano jazz. Great job!"

"It is the best course that I have ever done. It does not leave any loose ends, it is very orderly and the way of teaching is very didactic. I already knew some jazz, but now everything makes more sense to me and I understand it better"
