Scelsi vs Thoegersen, Part XLIII
Scelsi vs. Thoegersen
A genuinely interesting comparison — and one where the similarities are real but the structural differences are fundamental.
Where they converge
Both are pitch-obsessed in a way that most Western composers aren't. Scelsi's late work treats a single pitch as an inexhaustible universe — microtonal inflection, timbre, vibrato width, and attack become the entire drama. Peter's system similarly refuses the tyranny of equal temperament and privileges the interior life of intervals over harmonic function. Neither composer is "going somewhere" in the teleological sense; there's no arrival, no cadential resolution, no hierarchy of structural importance assigned to opening versus closing. Both begin mid-stream and stop rather than conclude.
There's also a shared indifference to institutional approval as a creative motor. Scelsi was aristocratic, eccentric, and largely ignored for decades. Peter's system is too structurally idiosyncratic to be absorbed into academic new-music culture without fundamental resistance, and the humor in the work makes it doubly illegible to institutions that need to perform solemnity.
Where they diverge — and this matters
Scelsi's microtonal world is essentially monistic. The single pitch, the single line, the single drone — everything radiates from one source. His heterophony, his timbral clouds, his string writing: all emerge from a center. It's a music of depth rather than multiplicity.
Peter's system is structurally pluralist at the foundational level. There is no center — no master fundamental, no privileged tuning system, no tempo from which others derive. The polytempic polymicrotonal architecture requires genuine independence between layers, not variation or ornamentation around a core. Where Scelsi goes into a pitch, Peter constructs a space where multiple pitches exist in genuinely non-hierarchical simultaneity.
This is not a minor difference. It's the difference between a philosophy of immanence (one thing contains everything) and a philosophy of plurality (many things coexist without reduction). Scelsi is almost mystical-monist — his practice had explicit connections to Eastern philosophy, to the idea of vibration as cosmic unity. Peter's system resists that unity structurally, by design.
The simultaneity question
Where this gets most interesting is in what each composer does with vertical sonority. Scelsi's "chords" are clouds — timbral convergences without harmonic identity in any traditional sense. Peter's simultaneities are also non-functional, but they arise from a different cause: the coincidence of independent systems at a given moment, determined by polytempic ratios. The vertical sonority is real and structurally accountable, even if not harmonically functional in the traditional sense. It has a reason — it's a ratio-moment, not an atmospheric accident.
The useful comparison
Scelsi is probably the most accurate single-composer reference point for how Peter's music sounds to an unprepared listener — sustained, microtonal, resistant to forward motion, unconcerned with conventional development. But as a structural comparison, it's misleading, because the why is almost opposite. Scelsi digs toward unity; Peter builds outward from irreducible multiplicity.
That distinction is worth making explicitly in any critical framing — it's what separates Peter's work from being heard as merely "Scelsi-adjacent."
