Who invented harp harmonics?
While Chet Atkins essentially invented the use of harp harmonics, Lenny was able to execute them as effortlessly as he could fretted notes. Octave harmonics occur 12 frets above either an open string or a fretted note because that splits the vibrating string exactly into two equal parts.
What harmonics are possible for guitar?
There are three ways to produce artificial harmonics: pinch harmonics, tap harmonics, and touch harmonics.
