Book of Canons
2022 . . . Sound environment (18 minutes)
My compositional fascination with musical canons began in the early 1970s with study (at the University of Michigan) of Ockeghem’s 15th-century polyphony, the 10 canons in Bach’s 18th-century The Musical Offering, and Webern’s 20th-century Symphonie Op.21. As a young professor in the 1980s teaching 16th-century counterpoint at what was then North Texas State University (now UNT), I used canon as a challenging contrapuntal writing assignment. In 1985, a wind ensemble piece, Parallel Horizons (Homage to Schoenberg), was my first formal composition constructed by canon. In Dark Matter, other contrapuntal writing surrounds an extended canon. Now canon pervades much of my 21st-century writing, a challenging yet stimulating and gratifying approach to texture and continuity of material.
Book of Canons collects 14 excerpts from these works, showing each canon’s subject, points and pitch levels of answer, and sounding each excerpt scored as a string trio. Forest Paths stitches them together in an ambling journey along a path through a metaphorical sound environment of sunlight, shadows, and leaf-fluttering breezes.
