The popularity of the clarinet in Spain is second only to that of the guitar, and there is a rich tradition of clarinet playing that is accompanied by an equally rich repertoire of music for the clarinet by Spanish composers. The works for clarinet and piano by Miguel Yuste (1870-1947) are among this little known repertoire. In the early twentieth century it was thought that Miguel Yuste wrote over one hundred works for clarinet. However, current research suggests that this is incorrect. What is known is that seven works for clarinet and piano have been published. Miguel Yuste and his music are pivotal in the establishment of the strong clarinet tradition for which Spain is presently known. In his thirty years as the clarinet professor at the Real Conservatorio Superior de Música de Madrid (1910-1940), Miguel Yuste's music and pedagogical ideas became, and continue to be among the foundations of Spanish clarinet playing. This project discusses each published work and presents current research on the works composed for clarinet and piano by Miguel Yuste. After a brief history of Spain's music and social climate in which it developed (Ch. 2), this document discusses the introduction of the clarinet in Spain, clarinet pedagogy at the Madrid Conservatory (Ch. 2), and Miguel Yuste's influence within that pedagogy (Ch. 3). Establishing contact with living clarinetists whose music education was directly influenced by Miguel Yuste and/or his students provides invaluable insight into the traditional performance practice of the works and the extent to which Miguel Yuste influenced Spanish clarinetists in the twentieth century. Chapter four presents an annotated bibliography and brief discussion of the extant works for clarinet by Miguel Yuste. Each annotation includes the title of the work, publisher, date of publication, duration, and any commercially available recordings.
