Stefania Turkevych's Heart of Oksana (1969): A Critical Edition of a Lost Ukrainian Opera
Bibliographic record
Abstract
abstract: It is no secret that the Soviet Union silenced the voices of many artists, but pieces of this history are still emerging—including the story of Ukraine's first female composer to achieve professional renown: Stefania Turkevych (1898-1977). Although the quantity and quality of Turkevych's compositional output should have established her as a major international figure, most of her work remains unpublished. Turkevych is absent from both Grove Music and Die Musik in Geschichte und Gegenwart (MGG Online). There is a clear need for English-language biographical materials about Turkevych and for publication of her works.\n\nThis document represents the first critical edition of Turkevych’s three-act chamber opera, Серце Оксани (The Heart of Oksana), commissioned in 1969 for the 100th anniversary of the creation of Canada’s Province of Manitoba (and its subsequent settlement by members of the Ukrainian diasporic community). The score is prefaced by brief introductions to both Turkevych and Серце Оксани as well as an explanation of editorial procedure and a critical report.\n\nLost Soviet-era voices carry particular social and political weight as present-day Ukraine reclaims an identity that moves beyond reductive “Russian vs. European” dichotomies, and solidifying that identity seems even more urgent against the backdrop of the current Donbass War (2013-present). This project represents the first step in a much longer-term effort to unearth and share Turkevych’s story and overlooked contributions as a composer, teacher, and lifelong advocate of Ukraine’s language and culture.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
