"This is the only course about improvisation that really gets you to improvise from the start. Using your ears and developing your inner voice. I can honestly say that Jelske is the best teacher I have come across."Eef van der Burg (saxophone, Netherlands)
"A very important thing that this course has done for me is to help me realize that I really CAN improvise! Through my studies with IFR, I feel like I am finally starting to find my own musical voice. This has really boosted my confidence."Ed Wasiak (trumpet, Canada)
"The IFR method is explained so well, so understandable and logical with beautiful backing tracks to improvise with. The approach is so clear and simple. Why had no one ever told me this before? IFR has helped me enormously to jam and improvise over jazz standards and other songs."Annemarie Post (tenor saxophone, Amsterdam, Netherlands)
"IFR is the key that opened everything musical to me. When I started learning the saxophone, one of the goals I had was to be able to jump into any playing situation, to pick up my horn and make improvised solos on the spot. To me, that made someone a real musician. I am now that kind of musician because of IFR."Woody Haiken (saxophone, Cottonwood, Arizona)
