Meaning: This quote by Brian Ferneyhough sheds light on his compositional approach, specifically his use of modified cyclic form in creating musical structures. Ferneyhough is a prominent contemporary composer known for his complex and intricate compositions that often push the boundaries of traditional musical forms and structures. His approach to composing, as highlighted in the quote, provides insight into the meticulous and innovative methods he employs to create his music.

The concept of "modified cyclic form" mentioned in the quote refers to a compositional technique where the metric structure of a piece is organized in a cyclic manner, with each cycle undergoing some form of variation. In music, the term "metric structure" refers to the organization of beats and rhythms within a piece, and cyclic form involves the repetition of a musical pattern or structure. Ferneyhough's modification of this form suggests that he introduces variations within each cycle, adding complexity and depth to the overall structure of the piece.

One of the key elements of Ferneyhough's approach is the idea that "measure lengths" serve as "concrete musical 'material.'" This indicates that he views the duration and organization of individual measures as tangible building blocks for his compositions. By treating measure lengths as musical material, Ferneyhough is able to manipulate and transform them in a manner akin to working with physical substances, highlighting his meticulous attention to detail and the intrinsic musical properties of rhythm and time.

Ferneyhough's use of cyclic form and variation aligns with his broader compositional style, which often features intricate rhythmic patterns, complex textures, and densely layered structures. His music is characterized by its demanding technical requirements and the exploration of extended instrumental techniques, making it a challenging yet rewarding experience for performers and listeners alike.

It's important to note that Ferneyhough's approach to composition reflects the influence of modernist and avant-garde traditions, as well as his interest in exploring new possibilities within contemporary classical music. His innovative use of modified cyclic form aligns with the broader trend of experimentation and expansion within the realm of contemporary composition, where composers seek to push the boundaries of traditional forms and structures.

In conclusion, Brian Ferneyhough's quote provides valuable insight into his compositional techniques and philosophy. His use of modified cyclic form, coupled with the concept of measure lengths as musical material, underscores his meticulous and innovative approach to creating complex musical structures. This approach is emblematic of his broader contribution to contemporary classical music and highlights the ongoing evolution of compositional practices in the 20th and 21st centuries.
