Few elements in a church service can vary in length quite as much as the celebration of Holy Communion. Due to the number of people present during a given week's service, the speed of the servers, last-minute changes to accommodate parishioners in need of assistance, and other unforeseen scenarios, all of the pieces in this volume are of extendable length-sections are clearly designated for possible repetition. Each piece is based on the melody of a familiar communion hymn.
