There are composers who try to fill the world with sound, and then there is Rytis Mazulis, who calmly takes a single semitone, places it under a microscope, and proceeds to dissect it as if time itself were a specimen slide. "Tempered Tempus", released by Music Information Centre Lithuania, is less an album than a controlled experiment in perception. Two pieces, just under an hour in total, and enough micro-intervallic tension to make your inner ear question its own career choices.
Mazulis has spent decades refining what is often described as radical minimalism, though “minimal” feels misleading. There is nothing sparse about the psychological density of this music. Born in 1961, trained under Julius Juzeliunas, later head of the Composition Department at the Lithuanian Academy of Music and Theatre, and recipient of the Lithuanian National Culture and Arts Prize, Mazulis has built a reputation not by multiplying materials but by restricting them until they combust. His work has long circulated internationally, yet this is the first portrait album issued in Lithuania since the late 1990s, marking the beginning of a two-part cycle. The timing feels deliberate, almost defiant.
Schisma (2007) is the first incision. The title refers both to the acoustical term for a minute interval in tuning systems and to the idea of a split, a fracture. The half-tone is divided into the smallest audible units; time follows suit. The result is a polyphonic micro-canon for cello and fourteen virtual instruments, each operating at its own slightly divergent tempo. The performer, Anton Lukoszevieze, stands at the centre of this vortex, bow in hand, threading a “melody” that feels increasingly unstable as its harmonic ground dissolves into hairline cracks.
Listening to "Schisma" is uncannily clinical. The texture resembles a diagnostic procedure for the brain’s tolerance of ambiguity. Intervals hover in the uneasy space between consonance and abrasion. The canon is strict, but its strictness produces vertigo. One becomes aware not of thematic development in any conventional sense, but of microscopic displacements accumulating over time. The piece does not shout; it insists. It demands a specific kind of attention, one that accepts multipolarity as a basic condition. Endurance is required, but not as punishment. More as initiation.
If "Schisma" is about fracture, Solipse (2018) turns inward. Commissioned for the Tectonics Festival in Glasgow and dedicated to Lukoszevieze, it is conceived for cello and phonogram, the electronic layer realised in collaboration with Julius Aglinskas. Here, micro-intervals are arranged according to a statistically derived arithmetic progression. That sounds dry. It is not. The gradual expansion of pitch space creates a slow, hypnotic drift, as if the music were exhaling in increments too subtle to measure without instruments.
The title suggests solipsism, and indeed the piece feels monistic: a single consciousness unfolding within itself. The cello line interacts with its pre-recorded double in a dialogue that never quite becomes a duet. Instead, it is a mirroring process, slightly misaligned, producing a shimmering hyper-dissonance. Mazulis’ frequent use of computer technology underlines the repetitive principle, yet the live instrument keeps the texture alive, imperfect, almost vulnerable. The transformation is glacial, but it is real. By the end, one’s sense of temporal proportion has shifted, quietly but irrevocably.
Lukoszevieze proves an ideal interpreter. Founder of the experimental ensemble Apartment House and a longstanding advocate of contemporary repertoire, he approaches Mazulis’ demands not as exotic challenges but as natural extensions of musical practice. His tone remains focused even when the harmonic field fractures into microtonal dust. The recording, made at the Music Innovation Studies Centre in Vilnius, captures this balance between austerity and organic resonance with remarkable clarity.
Recent events underscore Mazulis’ continued relevance: a new version of "Canon Mensurabilis" premiered at the 2025 Huddersfield Contemporary Music Festival, and a nomination for the Prince Pierre of Monaco Foundation’s Musical Composition Prize places him firmly within a broader European conversation. What distinguishes him, however, is not institutional recognition but consistency of vision. Few composers pursue a single idea so relentlessly without collapsing into self-parody.
"Tempered Tempus" does not offer comfort listening. It is precise, ascetic, and occasionally unnerving. Yet within its narrow parameters lies a strangely expansive experience. By subdividing pitch and time to near-absurd degrees, Mazulis opens a space where perception itself becomes audible. The album feels like a study in limits, and in the quiet ecstasy that can emerge when those limits are accepted rather than denied.
One finishes the disc slightly altered, as if the internal clock had been recalibrated by a patient, uncompromising hand. Not many records can claim that. Fewer still would dare try.
