Three works by Tippett stand together among his compositions because of their similarity of subject and performance medium. All are large works for soloists, chorus and orchestra, on meditative librettos, and intended for unstaged presentation. Only A Child of Our Time is given the genre designation "oratorio" by Tippett. An in-depth analysis of these works and the model for A Child of Our Time, Handel's Messiah, reveals that though they neither present religious subjects nor, in the case of The Vision of Saint Augustine and The Mask of Time, exhibit traditional formal divisions associated with oratorio, Tippett's works do indeed belong to the oratorio repertoire of the twentieth century.

Music printing in the United States between 1825 and 1900 was in a constant state of change as older techniques improved and new processes were invented. Beginning with techniques and traditions that had originated in Europe, music printers in America were challenged by the continuous problem of efficiently and economically creating ways of transferring a music image to the printed page. This study examines the music printing techniques, equipment, and presses of the period, as well as the progression from music type to engraved plate and lithograph stone. A study of the techniques of altering music printing plates helps explain the differences occurring in prints from the same edition and will help further our understanding of this important aspect of music historiography.

Dubuisson (fl.1666-c.1685) is the sole French viol player-composer between Nicolas Hotman (1613-1663) and Le Sieur de Sainte-Colombe (d.c.1700) whose works are extant. His four suites from a Library of Congress manuscript (1666) are the oldest dated French music for the bass viol; his approximately 125 pieces are contained in five manuscript sources. This thesis brings together, for the first time, all the music from the five sources for study and analysis. Together with the few biographical details, this material is used to assess his position within the French viol school. Brief histories of the viol and the suite in France precede a discussion of Dubuisson's contributions to the evolution of the genre.
