William Mason (1829–1908) was a well-known American composer, pianist, and pedagogue. Researchers have mainly focused on Mason's career as a pedagogue in the United States and his pedagogical treatises, which are widely considered and used as the conceptual core of teaching materials on the nineteenth century. However, there has been only an annotated catalogue of Mason's music works, and no performance guide to his piano compositions. This dissertation is designed to be the first performance guide to his solo piano repertoire and act as an introduction to his music through an examination of selected works suitable for the intermediate student. This study provides instruction for students on how to practice these works through the analysis of the elements of practice – pedaling, phrasing, technique practice, touch, and musical expression – which were all considered as essential by Mason himself for a good performance. The five piano works selected are: Three Preludes, Op. 8, No. 1; Ballade et Barcarole, Op. 15; Valse Caprice, Op.17; Spring-Dawn, Mazurka–Caprice, Op. 20; and Spring Flower–Impromptu, Op. 21.
