Adrian Willaert and the Theory of Interval Affect - Scholarly

In this review of Adrian Willaert and the Theory of Interval Affect, Timothy R. McKinney presents a focused scholarly reconstruction of Willaert's musical thought that will most appeal to musicologists, advanced students, and historically informed performers. The book's single biggest selling point is its methodical use of Willaert's surviving compositions to infer a coherent theory linking specific melodic and harmonic intervals to expressive meaning, a topic previously attributed to later theorists; this review explains why that approach matters for understanding Renaissance practice and interpretation.

Key Features

• Historical reconstruction: McKinney derives theoretical claims from Willaert's actual music, offering readers a concrete way to see how interval choices produce affect in practice.
• Contextual linkage: The book connects ideas found later in Vicentino and Zarlino back to Willaert, clarifying the lineage of the theory of interval affect.
• Analytical focus: Detailed musical examples make it possible to follow the argument step by step and evaluate how intervals function in expressive terms.
• Readable scholarship: The prose balances academic rigor with accessibility so that advanced students and informed performers can apply the concepts to repertoire.
• Specialized scope: By concentrating on interval character rather than broad aesthetic claims, the book provides a precise toolset for interpretation.

Who It's For

The book is best for musicologists, graduate students in historical music theory, and performers specializing in Renaissance vocal and instrumental repertoire who want a principled way to link interval choices to expression. Readers seeking a deep dive into how descriptive labels like major and minor functioned as sonic characters rather than simply size distinctions will find this reconstruction useful.

It is less suited to casual listeners or beginners in music theory who expect a general survey of Renaissance music; the work assumes familiarity with modal practice, interval terminology, and close musical reading, so novices should look for more introductory texts first.

Pros & Cons

Pros

• Grounded in primary sources, the book gives a convincing basis for attributing ideas to Willaert through his compositions.
• Clarifies the historical development of interval theory from Willaert to later theorists, aiding contextual understanding.
• Analytical examples make the argument usable for informed performance decisions.

Cons

• The specialized focus means readers must have prior theoretical knowledge to fully benefit from the reconstruction.
