Plus Minus (Score): Chamber Ensemble

Tsao has created something rare: a realization of Stockhausen's Plus Minus that respects the open score's serial thinking while making it performable and dramatically coherent. This 30-minute work doesn't simplify or domesticate the original; instead, it stages a genuine artistic conversation with mid-century complexity. Programming this signals to your ensemble that experimental modernism remains vital and playable.

Plus Minus occupies a conceptual space between order and freedom, where serial structures generate unexpected sonorities and instrumental combinations. The dialogue between the two instrumental groups creates a sense of layered discovery; listeners experience both careful planning and spontaneous interaction unfolding simultaneously.

Advanced chamber ensembles ready to engage with post-1945 modernist thinking and the specific compositional legacy of Stockhausen. This work suits festival programs, contemporary music series, and university chamber groups that value intellectual rigor and experimental heritage alongside technical skill.

• Study Stockhausen's original 1963 open score alongside this realization to understand how Tsao navigated the indeterminacy and made specific musical choices where the original leaves room for interpretation.
• Balance the two instrumental layers carefully during rehearsal: the trio (cello, piano, clarinet) and the second group (trumpet, trombone, percussion, guitar, accordion) should remain distinct yet interdependent.
• Pay close attention to the ensemble's internal rhythmic coherence. Though the score emerges from serial procedures, the performers must listen actively to maintain ensemble unity across these two stratified groups.
• Allocate substantial rehearsal time to understanding the harmonic and textural language. This is not a piece that yields to surface-level reading; deep familiarity with the score's architecture rewards preparation.

Position this on a concert focused on twentieth-century modernism or as part of a series exploring Stockhausen's influence on contemporary composition. Its 30-minute duration and advanced demands suit a dedicated chamber concert or a festival program where the audience has come specifically for experimental repertoire.

• Reading and interpreting complex contemporary scores with multiple independent layers
• Ensemble balance and listening across non-traditional instrumental combinations
• Understanding serial compositional procedures and their sonic outcomes
• Collaborative interpretation of open-form and semi-indeterminate notation
• Sustaining focus and coordination in extended modern works
