Week Five is apparently a guitar-lite week, with three days of keyboard-related images, as well as a rare percussion day — the most basic of drum rudiments. The second day has some cool higher-fret chord voicings, though.
The “book” (if it is ever compiled as such) is divided in 18 weeks, which we think is the length of a high school semester. Each week has five work days, so that might fit nicely into school periods. Basically, this “coffee table book” really wants to be a “textbook,” without being so wordy.
