Since February 2010, I have been endeavouring to comprehensively wade through Mark Levine's Jazz Piano Book - with variable success... I set a rudimentary timetable, for how if I was able to spend a week on each chapter, I would be able to complete the book (a once over) in roughly six months: by July 2010.
The book is dense, and at times frustrating to follow (not all the elements are revealed in a chronological order: "later explained in Chapter 7" where a symbol has been used repeatedly without explanation for the previous three chapters!). But with the little I have done, I feel I have achieved a sense of reward and satisfaction in my ambition to decipher and make sense of one of the few books of authority in the Jazz education field.
