This LITTLE GUITAR BOOK THAT COULD showcases the C A G E D guitar chord and scale sequence exclusively in the TWENTIETH POSITION, for all to see and use. But, before thumbing through this book, there's exists certain musical material that the guitarist may need reminding of...even though he or she may have played for years. For example, in this book, six is the exact number of consecutive frets involved in the TWENTIETH POSITION, and that position spans a full two octaves plus a perfect fourth when in standard tuning. Plus in the TWENTIETH POSITION the second and third fingers on the fretting hand are to remain stationary in their respective frets or "slots", initially or at this point, as their stationary qualities allow the first and or fourth finger to stretch or slide to the outermost frets. And for the picking hand a very important string picking pattern occurs by the sound hole or bridge, where that hand naturally happens to be. The picking pattern involves every other string and is best evidenced when the C A G E D main root note sequence is plucked alphabetically, starting with the D root on the first or thinnest guitar string in this position. To become familiar with it, begin by picking the D there (first string, third finger); then E (third string, second finger); G (fifth string, third finger); A (second string, third finger); C (fourth string, third finger) and conclude with the D (sixth string, third finger). The one-three-five, two-four-six string pattern naturally fits the fingers on the picking hand and the pattern is looped, forwards or backwards (six-four-two, five-three-one) as the D roots on the first /sixth string(s) are deemed interchangeable. THE LITTLE GUITAR BOOK THAT COULD also uses three musical terms that need clarification for its purposes...those terms being main root notes, octaves and unisons. What are main root notes one might say? Well, generally speaking, main root notes represent a specific set of root notes that fall or cluster under the second and third fingers of the fretting hand when in a guitar position. Once the location of each main root note is learned under the second and third fingers, the attention then moves to their octaves. Now, an octave is defined as the musical distance or interval between one musical pitch and another with half or double its own frequency. Some correctly call the interval a "perfect octave" proper, but to simplify, in guitarland, octaves are usually "one string one fret away" on the fretboard. This handy fact helps to memorize the neighboring octave in the given position, even though, occasionally, two strings and or two frets are involved (the same concept applies in that there will be some sort of string skipping). And last are the unisons, which occur when two or more music notes happen to sound the exact same pitch. In guitarland, it usually means "same note different string or fret", implying that the unison occurs in the guitar position at hand, that being the TWENTIETH. This book then ultimately concludes with an A B C D E F G A alphabetical appendix, in which the C A G E D material is thus reorganized alphabetically to include the B and F material. So that's it! THE LITTLE GUITAR BOOK THAT COULD for the TWENTIETH POSITION is uncomplicated, straightforward and super easy to use. Its picture worth a thousand words visual based format allows the guitarist to take full advantage of the fretboard material straight away. You'll have fun discovering some fresh perspectives on the same old same old, while also adding some new twists and turns to your own technique. THE LITTLE GUITAR BOOK THAT COULD for the TWENTIETH POSITION also contains copious amounts of manuscript and tablature paper too, helping you catalog your musical ideas, keeping them like a journal of sorts!. As always, thank you very kindly for including THE LITTLE GUITAR BOOK THAT COULD in your repertoire of fretboard knowledge needs...Enjoy!
