Brilliant. Practising with this book really puts you “inside” the changes! I recommend this book highly.

I like the approach and started writing impro etudes myself. I think I’m learning a lot this way.

I like the book. I’ve been a tenor saxophonist for 15 years and I use it very often to improve my technique and my vocabulary!!

Very usefull and instructive book!

It’s great to get the students started on concepts for improvisation.

I am already starting to notice a difference in the way I am thinking and hearing things. I was stuck into a vertical way of thinking and this book has got me on a linear path within a week of using it. I am also finding my sense of time and rhythm has improved dramatically. Thanks for putting this out there. – Owen Johnston (per email)
