Adolf von Henselt (1814–1889) was one of the most renowned German pianists and composers of his day. The majority of his compositions are for the piano, one of his most successful being the set of Piano Études, Op. 2. It consists of twelve etudes, each of which is designed for developing a particular technique. Henselt's etudes are as demanding as Chopin's and Liszt's, so this pedagogical guide is designed for advanced-level students. Henselt uses many finger extensions and stretches larger than an octave, which may be difficult for smaller hands to play, but proper flexibility and relaxation should enable all students to play them. This dissertation describes the specific technique for six selected etudes and provides exercises to help students learn each technique effectively. The selected etudes—Nos. 1, 2, 3, 6, 9, and 11—were chosen to cover all three technical levels of less-advanced, advanced, and very advanced as well as a variety of musical styles and technical challenges.

Sergei Rachmaninoff's Second Piano Concerto is one of the most frequently performed and beloved works. It is ironic that, however, despite its huge popularity, there are not many in-depth studies of this concerto, offering pianists few opportunities to examine the work from an analytical perspective. The detailed analysis presented in this study reveals that the main structure of this concerto is directly related to a motto comprising three-notes, designated the 6-5-1 motto. In his use of this motto in the Second Piano Concerto, Rachmaninoff was profoundly influenced by the German-born composer Adolf von Henselt. Indeed, while von Henselt's importance for Russian music has been generally recognized, his impact, especially upon Rachmaninoff, has received insufficient attention in the scholarly literature. This study also examines Henselt's Piano Concerto Op. 16 in depth in order to demonstrate how Rachmaninoff's masterwork relates to its precursor. Additional studies of the 6-5-1 motto in European compositions from the nineteenth century trace the motto's origins.
