The text is translated into English by the composer from the original Latin and Greek. It comprises twelve movements, and a performance is approximately fifty-five minutes in length. The work serves as a continued exploration of composing for brass, begun in 2010. The work is constructed primarily from the tetrachordal triadic supersets--that is, tetrachords based on major and minor triads--connected through parsimonious voice-leading. Rest is my third mass in a series of works in various languages composed for various ensembles.en-USCreative Commons BY-NC-ND 4.0-USBrassRequiemElectronic Thesis or Dissertation
