This thesis on the Rise of the French Organ Symphony refers especially to the relevant works of Alexandre Guilmant and Charles-Marie Widor. It commences with a survey of the historical background, dealing with the development of French organ music from the 16th to 19th Century and the development of organ building in France from the 17th to 19th Century. It then proceeds to descriptions of the organs of St Clotilde, La Trinité and St Sulpice Churches in Paris, which are followed by biographical profiles of Cesar Franck, Alexandre Guilmant and Charles-Marie Widor, respectively. The major part of the thesis is devoted to a detailed analysis of the organ sonatas of Guilmant and the organ symphonies of Widor, which are discussed from the point of their cyclic outline and aspects of form and of style. The final chapter summarises the major findings of the analytical research and evaluates by comparative method, the merits and achievements of the two composers. In addition, Appendices are attached, providing specifications of various French organs and pictorial material relevant to the thesis. A separate cassette tape features characteristic sounds of Cavailie-Coll organs.

The lecture recital was given on November 20, 1979. The final movement of Widor's Symphonie Gothique, opus 70, the first movement of Widor's Symphonie Romane, opus 73, and the first movement of Dupré's Symphonie-Passion, opus 23 were performed following a lecture on Gregorian Chant in the organ symphonies of Widor and Dupré. The lecture included a brief historical discussion of the decline of organ literature following the French Classical School, the development of the Modern French Organ School beginning with the establishment of the organ department at the Paris Conservatory, the revival of plainsong and the establishment of the School of Solesmes, and the influence of César Franck and the organ symphony. The main body of the lecture included biographical sketches of Widor and Dupré, a discussion of the general characteristics of their organ symphonies, with the emphasis upon those movements specifically employing the use of Gregorian chant.
