This dissertation consists of four programs: one lecture- recital, two recitals for piano solo, and one (the Schubert program) in combination with other instruments. The repertoire of the complete series of concerts was chosen with the intention of demonstrating the ability of the performer to project music of various types and composed in different periods.

Inasmuch as this investigator can determine, no major study has been done concerning music's relation to the "isms" selected for this discussion. The contemporary interest in the movements themselves has been so widespread that the documentation of them, in scattered accounts, is enormous. It is disappointing that these records provide little or no information about the musical aspects of the movements; the graphic and literary accounts, on the other hand, have been accorded generous treatments. Since futurism, cubism, and surrealism, in their origins, were oriented toward the visual and literary arts, it is not surprising that these two aspects would receive the greatest amount of attention.

The third recital was the lecture recital: Registration of Orchestral Textures in Organ Music. This lecture was an attempt to deal with the contemporary problem in performance practice of registration of Romantic organ music.
