EBDGBD tuning was inspired by guitarist Will Ackerman’s FCE♭A♭CE♭tuning, which requires you to tune most of the strings up by as much as a minor third (A–C, for example). But Doug realized that if he tuned that tuning down a half step, he got EBDGBD, which is the same as standard tuning with the A string raised to B and the high E string lowered to D, and creates a nice Em7 chord. He uses it to play “The Foggy Dew,” an Irish song written in the early 20th century. Doug shows you chords for EBDGBD tuning in this video.
