  • EFFULGENCE II

    2023 . . . sound sculpture . . . duration 4:40

    EFFULGENCE (the word means “brilliant, shining radiance”) was a 1984 improvisatory composition in the style of Terry Riley’s In C, overlapping repetitive patterns I call multi-phase ostinato music. It was like the rhythmic dance of a fountain.

    This sequel evokes the speckled field of sunlight reflected on the surface of a body of water. My home state, Michigan, The Great Lakes State surrounded by three of those magnificent fresh-water seas, also contains over 1,000 smaller lakes. My whole life I have gazed at and studied the way sunlight reflects off their wave-articulated surfaces, sparkling in a complex ensemble dance of periodic flashes of light.

    The musical construction is all about prime numbers. The melodic-cell eighth-note theme consists of successive intervals of 1, 3, 5, 7, and 11 semitones. Rhythmic values and motivic repetition cycles are all durations equivalent to 1, 3, 5, 7, 11 or 13 eighth-notes.

    2021 . . . percussion trio . . . duration: 10 minutes

    Horizon . . . Thunder . . . Squall . . . Sun sparkles . . . Powerful waves

    The music is fashioned out of a small set of sound resources: simple sounds of drums, bright sounds of ringing metal instruments, and deep shining sounds of tam-tams. The piece is about these distinct timbres – only the sparkles employ any pitch constellations, and then just one “chord” that recycles kaleidoscopically. Most of all, the piece is about time and its articulation in free, ametric rhythm. In Thunder and Waves, the time patterns are governed by the digits of the magical numer Pi. In Sparkles, the timed recurrence of each pitch is determined by prime numbers. Both number schemes transcend periodicity, letting time float.

    Growing up in the Great Lake State, being surrounded by three of the five Great Lakes formed a big part of my Michigander character. Since many summers working at what was then called the National Music Camp in Interlochen, my favorite was the closest, Lake Michigan. Its magnificent coast forms the western edge of the lower peninsula, stretching from New Buffalo all the way up to the Straits of Mackinac. Its waters reach from many Michigan harbor towns across to Chicago and Milwaukee. Its varied environments offer fascinating features such as sand dunes, ice dunes, and remote islands. This piece depicts three phenomena: approaching thunder echoing across the vast lake; sunlight sparkling on the cold surface; and eternal, powerful waves.
