Reviews of professor Hans Jensen

Rating: 5.0/5, difficulty: 5.0/5
Hans Jensen has saved my life. With his innovative book, CelloMind, he has singlehandedly improved the intonation of every single person alive. If he had never told me about the syntonic comma, I might still be struggling to play the Kodaly Solo Sonata; now that I know the comma of Didymus is approximately 22 cents, I can be free in my performance.
