Books (print / ebook / audio):
My currently favorite book:
The music lesson: A spiritual search for growth through music. By Victor Wooten. While you can read this book in print or ebook-formats, listening to it as audio in form of a radio play or “soundtrack” is unbeatable. You can find audio excerpts of the original or readings by individuals on YouTube. Also, you can listen in to the audio at Audible. There is a sequel to this book by the same author which is next on my reading or listening list: The spirit of music: The lesson continues.
Also:
Effortless mastery. By Kenny Werner. Available in print, ebook, or audio format.
The inner game of music. By Barry Green and W. Timothy Gallwey. Available in print, ebook, or audio format.
