In this bite-sized lesson, Derek Trucks gives you some insights on incorporating natural and artificial harmonics into your slide lines.
From Derek: "I learned this technique from the sacred steel players. Using harmonics is a great way to get a phrase to jump out of the mix, especially when playing live.
"There are two types of harmonics: artificial harmonics [A.H.], which are sounded from “fretted” notes, and natural harmonics [N.H.], which are sounded from open strings. In this lick [FIGURE 5a], I generate an artificial harmonic by placing the slide on the high E string at the eighth fret while simultaneously picking the string and lightly touching it with my pick-hand index finger exactly 12 frets higher, directly above the 20th fret. The result is an artificial harmonic that sounds one octave higher than the original note.
"In this lick [FIGURE 5b], I start with a natural harmonic that’s sounded by lightly touching the high E string at the 12th fret while picking it conventionally. This produces a harmonic one octave higher than the open string. I then begin with the slide from behind the nut and quickly slide up to the 17th fret so that it raises the pitch of the harmonic."
