I decided to learn jazz piano, and not having any music background whatsoever, decided to start with Book 1 of this series. The books build a foundational knowledge within a surprisingly short time. I'd say one can do 1-3 lessons per hour depending on one's aptitude for the particular section, so the pacing is mostly well balanced. I plan to continue this series. I've also found it helpful to reinforce knowledge and build skills using a couple of iPad apps for music sight reading. One negative note about the first two books: I found the ear-training exercises (via the separate CD) to be quite above my level, but a necessity.
