A harmonics is a chime like sound created by lightly touching a vibrating string with the left hand at certain points along the fretboard.
The left hand must be positioned directly above the fret just touching the string (i.e., without pressing down). Harmonics are most easily played on the 12th, 7th and 5th frets. In the following example harmonics are played on the 7th fret of each string.
Harmonics are also useful for tuning the bass guitar (see appendix on tuning). To get a brighter sound, which is essential when playing harmonics, position the right hand closer to the bridge (back pick-up).
The following two examples incorporate harmonics.
Now try applying harmonics to a Blues ending. Let the last four notes ring together.
The following three examples introduce three Blues composite styles: Rock-Latin Blues, Reggae Blues and Blues Funk.
