There are very few significant sonatas for flute and piano written between 1880 and 1918, a period of unusually rich stylistic diversity. Gabriel Pierné composed his Sonata in D Minor, Op. 36 for piano and violin in 1900, and later transcribed it for flute and piano. Unfortunately, the work has not been embraced to a significant extent by either violinists or flutists. The wealth of violin sonatas from this period might explain it not becoming part of the canon for violinists, but this is not the case for the flute repertoire, where it seems that it should hold a place of genuine importance. Since little has been written about Pierné as a composer or about this piece in either of its versions, this project is intended to promote an understanding of the work in its historical and theoretical context and to advocate for more frequent performances. This document also suggests an alternate version of several particular passages so it can better represent the characteristics of today's flute and its modern techniques. This research will help other flutists and flute professors to introduce and spread an awareness of its existence and ideally helping to establish its place in the flute repertoire. From a historical standpoint, this dissertation also offers a case study of Gabriel Pierné's place, both stylistically and institutionally, in the history of French music in fin-de-siècle. Both of these goals fill important gaps in the existing research literature.

There is a puacity of original works from the Baroque Era for the guitar. Transcriptions, especially music originally for harpsichord, complement the guitarist's repertoire. Dominating the priviledged space in the guitar canon, represented by Baroque transcriptions, are the composers Johann Sebastian Bach, George Frideric Handel and Domenico Scarlatti. Underrepresented in the Baroque guitar canon is the music of Spanish composers, most noteworthy, the harpsichordist Padre Antonio Soler, who composed more than 120 sonatas for his instrument. Music is culturally defined and it is clear, through an analysis of the keyboard works of Soler, that his music was imbued with the salient features of his place and time. There is an implicit connection between the guitar and the non-guitar music produced in Spain as guitar gestures are part of the national emblem; this study makes an explicit connection between the harpsichord music of Soler and the modern guitar. The Spanish Baroque style, epitomized by the works of Soler, provide a clear objective for transcription. The current study produces a transcription of Padre Antonio Soler's Sonata No. R.27 and Sonata No. R.100, as well as an analysis of the sonatas to facilitate interpretation for performance and an explanation of the transcription process. The lacunae of Spanish Baroque guitar transcriptions that exists in the repertoire will be partially filled by adding Soler to the distinguished list of composers that currently inhabit the guitarists's library.
