David Lang: Love Fail

Contemporary choir is the umbrella for late‑20th and 21st‑century choral music written for professional chamber choirs, advanced collegiate ensembles, and skilled community choirs. It favors clear textures, flexible tonality (from lush pandiatonicism to modal writing), and sonorities built from clustered, added‑tone, and suspended harmonies. While much of the repertoire is a cappella, contemporary choir frequently incorporates subtle percussion, drones, electronics, and orchestral or chamber accompaniments. Texts range from Latin liturgy and vernacular sacred poetry to modern literature and newly commissioned libretti. Extended techniques—overtone singing, whispering, body percussion, glissandi, and aleatoric "clouds"—coexist with traditional legato blend and pure intonation.

Vocal ensemble refers to small-to-medium groups of singers (typically 3–16 voices) performing polyphonic or homophonic music with one or few singers per part. Unlike large choirs, vocal ensembles emphasize chamber-scale blend, clarity of individual lines, and intimate text delivery. The repertoire spans medieval conductus and motets, Renaissance madrigals and masses, Baroque part-songs, Romantic partsongs, and contemporary a cappella works. Ensembles often sing a cappella, but may be accompanied by continuo or instruments. Precision of tuning, diction, and balance among soprano/alto/tenor/bass (SATB) parts is central to the idiom.
