Ruminations on the Brian Eno A, hole chord: Alternative Voicings

A conversation between musicians James Blake and Brian Eno triggered this episode on what the latter calls the arsehole chord. This video discusses the chord structure: an incomplete extended chord in thirds, or, equivalently a form of tetrachord PitchClass Set 418. A voicing with an exposed open minor 9th interval yields a highly dissonant chord. Orchestration, timbre and register affect the perceived chord tension level. Alternatively close the minor 9th interval by inserting a new pitchclass and obtain extended chords in thirds, pentachord sets and twolayer polychords. These alternative voicing options are illustrated with short musical examples. Companion document (text, diagrams and score fragments, PDF, 24 pp. , A4) available on Patreon.
