Most guitarists have happened upon this style accidentally, and somehow think it’s just a “hit or miss” proposition as to when it can occur. The truth is this is an incredibly controllable style that has been perfected by many players such as Billy Gibbons, Roy Buchanan, Robbie Robertson, Danny Gatton and many others. I’ve heard these sounds referred to as “whistles,” “squeals,” “chirps” and, of course, “false” harmonics.
The main fact is that no matter what they’re called, they are unquestionably harmonics, and occur in certain high places where, if there were frets, they would be extremely small and very close together. Because of this, it is very easy to utilize all the harmonic overtone possibilities, such as the root, fifth, major third and seventh, all of which can be created while fretting the same note.
We will explore all of these approaches, and I will demonstrate this extremely dynamic and powerful style for you in a way that will dispel all of its mysteries. So, get your ears ready for this harmonic onslaught, because your playing will never be the same!—Arlen Roth
