This document is a formally-written scholarly text addressing in depth various topics related to my course of study. The research for the document draws from published literature, interviews with acknowledged specialists, and primary sources such as original manuscripts and published letters. The research will be divided into four chapters. Each chapter will discuss the significance of a selected work as illuminated through musical analysis, historical research, and/ or the discussion of performance techniques. The chapters will focus on Manuel Ponce's Sonatina Meridional, a biographical sketch of Agustin Barrios Mangore, the Prelude from J.S. Bach's B.W.V. 1006a E major lute suite, and Fuoco from Roland Dyens' Libra Sonatine.
