A Chord in Time

The augmented sixth chord, with its rich history and evolution, is explored through musical examples that highlight its significance from modal counterpoint to the tonal era. Dr. Mark Ellis offers a clear introduction to the chord's theoretical background, making it accessible for graduate studies. The book provides a chronological framework for analyzing its stylistic and harmonic contexts, culminating in a discussion of its impact on the decline of the tonal system and its continued relevance in the post-tonal era.
