The Fretless Bass

This book (precisely the tenth that I write about the bass) is a "journey" to discover what for me is the most beautiful instrument in the world, the fretless bass. I had in mind to do it for quite some time, since I always thought that there is too little material dedicated to the "fretless".
Together with the book, you will receive a link to download all the attached videos, audio examples and the backing tracks without bass!
