Santiago de Murcia (1673-1739) was one of the most prominent figures of the baroque guitar, both as composer and theorist. Despite his notability, his music and arrangements rarely find their way into the classical guitar repertoire. In modern guitar repertoire, it is common practice to arrange pieces from baroque composers such as Domenico Scarlatti, George Phillip Telemann, and Johann Sebastian Bach, none who wrote for guitar. My research involves doing an analysis of a historical transcription by Santiago de Murcia, and by doing so, share my insight into the possibilities, benefits, and idiosyncrasies of arranging baroque guitar works into the modern guitar. By analyzing Santiago de Murcia's Tocata de Coreli, a patchwork adaptation of Corelli's op. 5, my overarching objective is to empower modern guitarists to leverage this investigation and facilitate the creation of their own adaptations of baroque works. This documents not only the differences and similarities present in the original de Murcia manuscript print but how the study helped me develop a historically informed modern guitar transcription. Through this endeavor, I aspire to contribute to the broader discourse on the adaptation and preservation of baroque guitar repertoire within the contemporary musical landscape.
