The Arrangers' Lab

Voices of Gotham's performance of Arrangers' Lab member and Assistant Artistic Director Matt Gallagher's arrangement of "How Could I Ever Know?" from the musical The Secret Garden. Performed at the 2015 Barbershop Harmony Society International Chorus Competition in Pittsburgh, PA.

The Arrangers' Lab is Voices of Gotham's resident collective of composers who create and arrange new music in the barbershop harmony and contemporary a cappella styles. Already educated in significant university music programs, they apply their skills toward the study of the barbershop tradition and the ongoing development of its pedagogy and repertoire. They work in close collaboration with Voices of Gotham's artistic staff while continuing their own training at the Barbershop Harmony Society's Harmony University

In addition to providing Voices of Gotham and its affiliated quartets with custom material, the Arrangers' Lab also leads an ongoing Barbershop Arranging Workshop for members of the chorus at large. In the workshop, participants study existing barbershop arrangements, learn basic theory and composition, and gain insight and feedback on their work.
