In this final class of the Diatonic Triads series, we will explore clusters. Simply stated, a three-note cluster consists of any three consecutive notes from a seven-note scale. We will start with the notes C, D, and E from the C major scale.
While some of the inversions of this structure played as a chord may prove difficult or even impossible on some string sets and/or fretboard locations, we will explore all the possibilities with a view toward finding the most practical examples. When this tight structure is inverted and opened up, it can create more playable shapes and also provide surprisingly open-sounding and unique sonorities.
