One of the most popular series in the GIA catalog and the greatest single source of music for the contemporary ensemble. Accompaniments are scored for piano, with guitar chords, and typically, one or more orchestral instruments. The series contains editions with a cross section of vocal voicings: unison, two-part, three-part, SATB, descants, etc., and the majority of these editions include the congregation with their parts found on a back page reprint box.
