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, use and reference. But, before thumbing through this book, there's exists certain 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 remain stationary in their respective frets or "slots", initially at this point, as their stationary qualities allow the first and or fourth finger to stretch or slide to accommodate those notes found in the outer fret areas. And for the picking hand a very important string pattern occurs by the sound hole or bridge, where that hand naturally happens to reside. The 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, the guitar's utmost position. To begin, pick the D there (first string, third finger); then E (third string, second finger); G (fifth string, third finger); then A (second string, third finger); C (fourth string, third finger) and conclude with the low 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. This LITTLE GUITAR BOOK also addresses three musical terms that need clarification...those terms being main root notes, octaves and unisons. What are main root notes? Main root notes are those root notes that fall or cluster beneath the second and third fingers of the fretting hand when in a guitar position. Once they are learned, the attention then moves to their octaves. 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. Furthermore, in guitarland, octaves are usually "one string one fret away" on the fretboard. This handy fact helps to memorize the various octaves 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). The last term is the term unison, which occurs 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. This LITTLE GUITAR BOOK 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! This 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 musical advantage of the fretboard material straight away. You'll have fun discovering some fresh perspectives on your same old practice habits, while also adding some new twists and turns to your 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. Last, as always, thank you very kindly for welcoming THE LITTLE GUITAR BOOK THAT COULD into your library of fretboard knowledge needs...Enjoy!
