Bridge to Oblique Landscape (Distance in the Unison with Crosscutting Triangles) was produced in 2023 in response to an invitation from Fern Recordings (FR) to engage with Brian Eno and Peter Schmidt’s Oblique Strategies, a deck of cards designed to inform a creative process.
An interpretation of John Cage’s In a Landscape (1948) for piano or harp, a composition whose purpose, as influenced by Gita Sarabhai, is “to sober and quiet the mind, thus rendering it susceptible to divine influences.”
The composition is heard through Aircraft Halation, an arrangement of phantom musical glasses in a dual induction of 432 and 440 Hz tunings.
Eight sine waves are evenly spread between 432 and 440 Hz, and shifted between those bounds and their repetitions three octaves down with the spreads between 54 and 55 Hz. These frequencies are faded in and out of eight different virtual speaker positions with two moving and six in fixed locations. Sometimes multiple virtual speakers share frequencies, and sometime multiple frequencies share virtual speaker positions. Eight virtual speaker positions were chosen for their sound, and for being difference between 432 and 440 Hz.
Instances of triangles and their overtones cut across this array of experimental harmony.
