This article discusses a page of music manuscript, shelf no. MD-C-90 (4), preserved in a royal monastery situated in Madrid: the Convent of the Descalzas Reales. It contains three works for guitar, including two attributed to the Catalan composer and guitarist Fernando Sor (1778–1839). The first, entitled Minué de Sors, is known as Sor’s Op. 23, No. 6, while the second short composition, Alemanda desors [sic], is not yet officially attributed to Sor. While recent research has revealed that Salvador Castro de Gistau (ca. 1770–?), a publisher originally from Madrid, issued this same piece in his Op. 6 with the title Allegretto, the version found in the manuscript of the Convent of the Descalzas Reales provides a new perspective on this work, potentially by Fernando Sor. The third piece is a minuet (Minué) without attribution.
