For this lesson, I’ve put together a series of melodic riffs that could be used for a song’s intro, verse, chorus, bridge or solo section, and that utilize an open low E-string pedal tone. A pedal tone is defined as a long held or rearticulated note around which other parts move. As applied to the guitar, a pedal tone usually represents the tonic, or root note, and is played on the lower, often open, strings.
