... residue: A cappella

This piece demands singers to engage with contemporary vocal language in a fully acoustical setting, building ensemble confidence with advanced techniques while maintaining the intimacy that only a cappella singing can achieve. Dillon's writing challenges conventional harmonic thinking and rewards ensembles willing to inhabit unfamiliar sonic territory.

The piece unfolds through shifting layers of sound and silence, where every vocal gesture carries weight. There is both precision and vulnerability in the writing; moments feel sparse and exposed before building into dense, complex textures.

This work suits advanced high school or college choirs with experience reading contemporary notation and comfort with non-traditional vocal techniques. Singers should approach it as an ensemble willing to expand their technical and artistic palette.

• Map the extended techniques carefully during sectional rehearsals so singers understand not just what to do, but why each technical choice shapes the overall sound world.
• Pay close attention to the balance between structured passages and moments of freedom; rhythmic precision matters most where it's notated, but allow breathing room where the score permits.
• Schedule extra rehearsal time for intonation work, particularly in dissonant harmonic contexts where traditional reference points may feel unstable.

Program this alongside other contemporary a cappella works to create a concert that positions your ensemble as adventurous musicians. The 44-page length makes it substantial enough for a focused recital segment or as a centerpiece within a mixed repertoire concert.

• Reading and executing contemporary notational symbols
• Extended vocal techniques (including techniques beyond standard choral production)
• Intonation in atonal and microtonally-inflected harmonic contexts
• Ensemble blend and balance with unconventional sonorities
• Rhythmic independence and flexibility within structured frameworks
