George Frideric (or Frederick) Handel (1685 – 1759) was a German-British Baroque composer well-known for his operas, oratorios, anthems, concerti grossi, and organ concerti. He was born in Halle, Germany and spent his early life in Hamburg and Italy before settling in London in 1712, where he spent the bulk of his career and became a naturalised British subject in 1727.He was strongly influenced both by the middle-German polyphonic choral tradition and by composers of the Italian Baroque. In turn, Handel's music forms one of the peaks of the "high baroque" style, bringing Italian opera to its highest development, creating the genres of English oratorio and organ concerto, and introducing a new style into English church music. He is consistently recognized as one of the greatest composers of his age.

Orlando (HWV 31) is an opera seria in three acts by George Frideric Handel written for the King's Theatre in London in 1733. The Italian libretto was adapted from Carlo Sigismondo Capece's L'Orlando after Ludovico Ariosto's Orlando Furioso, which was also the source of Handel's operas Alcina and Ariodante. More an artistic than a popular success at its first performances, Orlando is today recognised as a masterpiece. Orlando (Roland), a great soldier in Charlemagne's army, falls desperately in love with the pagan princess Angelica, who is in turn in love with another man, Medoro. Orlando cannot accept this and he is driven to madness, prevented from causing absolute carnage only by the magician Zoroastro (who eventually restores his sanity).

The opera was first given at the King's Theatre in London on 27 January 1733. There were 10 further performances and it was not revived. The first production since Handel's lifetime was given at Halle, Handel's birthplace, in 1922. A production staged by the Barber Institute of Fine Arts in Birmingham, England, in 1966, conducted by Anthony Lewis, with Janet Baker in the title role, brought the opera back to London for the first time in over two centuries with performances later the same year at Sadler's Wells Theatre. The United States premiere of the opera was presented by the Handel Society of New York (HSNY) in a concert version on 18 January 1971 at Carnegie Hall with Rosalind Elias in the title role. The HSNY had made the first recording of the opera in 1970 in Vienna with a mostly different cast for RCA Red Seal Records. Peter Sellars directed the first staged production of the work in the United States at the American Repertory Theater on 19 December 1981. Countertenor Jeffrey Gall sang the title role and Craig Smith conducted.

As with all Baroque opera seria, Orlando went unperformed for many years, but with the revival since the 1960s of interest in Baroque music and historic performance practices, it has, along with most Handel operas, received numerous stagings both at festivals and in opera houses. Orlando was performed in London in abridged form in 1963 with Janet Baker in the title role.

Although originally written for Opera, I created this arrangement of the Aria: "Se fedel vuoi, ch'io ti creda" (If you want me to believe you faithful) from "Orlando" (HWV 31 Act I No. 11) for Flute & Strings (2 Violins, Viola & Cello).
