A Chord in Time

For centuries, the augmented sixth sonority has fascinated composers and intrigued music analysts. Here, Dr Mark Ellis presents a series of musical examples illustrating the 'evolution' of the augmented sixth and the changing contexts in which it can be found. Surprisingly, the chord emerged from one of the last remnants of modal counterpoint to survive into the tonal era: the Phrygian Cadence. This book will appeal to music analysts by providing a chronological framework for further stylistic and harmonic analysis. To ensure its accessibility in graduate classes, the author provides a straightforward introduction to the augmented sixth and its theoretical background. The book concludes with a discussion of the role of the chord in the decay of the tonal system, and its 'afterlife' in the post-tonal era.
