This post explores four-part quartal chord voicings on the three adjacent string sets through Major, Melodic Minor, Harmonic Minor, & Harmonic Major scale harmony.
These structures are often associated with Béla Bartók and McCoy Tyner and have become an important aspect of “modern” guitar playing.
Play through the following exercises. Try transposing these exercises into other keys once you become familiar with the various chord forms. Reduce the chords to three or two-string forms for more clarity.
