I called it up on Amazon and took a look inside -- basic fretboard patterns. Do not know how well it gets into why we are using those basic fretboard patters. My take on that.....
The song writer has placed a chord in a specific spot in the song so that it harmonizes with the melody. How does it do that? By sharing like notes with the active melody. So if a certain chord is active in the song - and we play notes of that chord we will harmonize with the melody and sound good with what is going on. Begs the question how many like notes? Just roots work. Roots and the fifth will play a lot of bass. The whole four note arpeggio, would be used in jazz. Most everything else is happy with the root, the five and the octave 8. Plenty of time for the correct 3 and 7. For example: R-R-R-R or R on the first beat and the five on the 3rd beat seems to work well. Then then generic R-5-8-5 kinda goes with the other stuff you may run into.
We do all that by getting arpeggio patterns into muscle memory.
Major arpeggio = R-3-5-7 and 8 if you like. Minor arpeggio = R-b3-5-b7 and again with the 8 if you like. Yes a dominant seven arpeggio would be R-3-5-b7. See a chord name and our fingers know where the notes of that chord are located.
Again, I do not have the book, but, it is giving you the basic arpeggio patterns you need. See a chord name and your fingers are going to it's notes.
I use patterns all the time, however, I just use one pattern. The major scale pattern and then adjust for what I need.
From the root the 2 is over two frets same string.
From the root the 3 is up a string and back a fret.
From the root the 4 is up a string same fret.
From the root the 5 is up a string and over two frets.
From the root the 6 is up two strings and back one fret. Right over the 3.
From the root the 7 is up two strings and over one fret.
From the root the 8 is up two strings and over two frets. Right over the 5.
A minor triad will have a b3 and if a 7 is used it'll be the b7. So using your major scale pattern adjust for the dominant seven, minor, diminished, augmented and sus or add arpeggios.
Find the root in first position and then add any extensions you like. Perhaps what I've given you will help make since of the patterns in the book. It is complicated unless you understand a few facts. The arpeggio has notes of the chord, if we play the arpeggio pattern when the chord is shown 9 times our of 10 we will harmonize with the melody and sound good with the rest of the song.
Now go to the book and don't skip pages.
This may come in handy:
Good luck.
