Mouyayoum: 16-Part Mixed Choir Choral Score

Mouyayoum stands apart as a choral work that treats the ensemble as a living instrument of constantly shifting colors rather than a vehicle for text or narrative. The 16-part writing creates possibilities for microtonality and overtone blending that challenge singers to listen with extraordinary precision, making rehearsals as much a study in acoustics and collective attention as in music-making.

The piece evokes the sustained, shimmering quality of overtone singing, with clusters of voices creating luminous harmonic clouds that seem to shimmer and shift even when the notation remains static. Over 13 minutes, the listener experiences a kind of meditative immersion in pure sonority, where individual voices dissolve into a unified, almost instrumental texture.

This work demands a choir with significant experience in contemporary music and the technical discipline to hold complex harmonic relationships over extended passages. It is ideal for university choirs, professional vocal ensembles, or advanced high school programs with a commitment to expanding their singers' technical and listening capabilities.

• Prioritize balance and blend over volume; the piece reveals itself through careful layering of parts rather than projection. Singers should listen across the ensemble and adjust their placement in the harmonic spectrum accordingly.
• Schedule multiple rehearsals devoted solely to intonation and tuning, especially where parts diverge microtonally. Use sectional work to establish each voice's role within the overtone series before bringing the full ensemble together.
• Conduct with minimal gesture once the ensemble has internalized the shifting harmonies. Let singers trust their ears rather than relying heavily on the baton for rhythmic or textural cues.
• Record rehearsals frequently so singers can hear the evolving sonority from outside the ensemble and develop awareness of their individual contribution to the whole.

Program Mouyayoum as the centerpiece of a concert devoted to contemporary choral music or as the culminating work of a program exploring non-Western vocal traditions and their influence on Western composition. Its introspective, immersive quality makes it particularly powerful when performed with minimal staging and subtle lighting that allows the audience to focus entirely on the evolving sound.

• Singing with precise intonation across complex harmonic clusters and microtonally-inflected intervals
• Listening across an ensemble to balance one's voice within a 16-part texture
• Sustaining focus and breath control over extended passages of minimalist or static material
• Understanding overtone series and the acoustic properties of choral blend
• Interpreting modernist notation and following a conductor through fluid, non-metric phrasing
