The lecture recital was given July 22, 1974. A discussion of the tientos of Cabezon, Aguilera de Heredia, Coelho, Correa de Arauxo, and Cabanilles included an analysis of eight specific works, a comparison of styles, and information about performance practices. The eight works were then performed. In addition to the lecture recital three other public recitals were performed, consisting entirely of solo literature for the organ. The first solo recital, on July 2, 1971, included works of Titelouze, deGrigny, Franck, and Alain. The second solo recital, on June 18, 1973, consisted of works by Bach, Klebe, Bruhns, Reger, Heiller, and Liszt. The final solo program, on June 7, 1974, included works by Boyvin, Buxtehude, Mozart, Alain, and Reger. All four programs, recorded on magnetic tape, are filed, along with the written version of the lecture material, in the North Texas State University library.
