The book was first published in 2005 through Krantz's website , and later became available through the Abstract Logix portal . The book has been translated into Japanese, with a Spanish translation currently under consideration. In 2019, Krantz and Abstract Logix released an updated version of the book, An Improviser's OS v.2, which clarified and expanded the core instruction of the first edition with new knowledge and experience gained by the author .
The book is divided into two parts: Part One explains the basic concepts and principles of the system, such as intervals, triads, pentatonics, modes, chords, and voice leading. Part Two provides exercises and examples for applying the system to various musical situations, such as soloing, comping, playing over changes, playing outside, and playing in different styles. The book also includes a glossary of terms and a list of recommended listening.
The book is not intended to be a comprehensive or definitive guide to music theory or guitar technique. Rather, it is a creative handbook that recognizes the potential irony of a creative artist concerning themselves with the math of music. The book encourages the reader to develop their own musical voice and personality through improvisation, rather than relying on patterns or licks. The book also emphasizes the importance of spontaneity, curiosity, and experimentation in the meeting of mind and spirit promised by contemporary improvisation.
An Improviser's OS is an essential handbook for anyone seeking to expand their vision creatively through music or other means. It is suitable for guitarists of all levels and styles, as well as other instrumentalists who want to improve their improvisational skills. The book can be purchased online through Abstract Logix or downloaded as a PDF file .
