Irish born British composer, teacher, conductor, and organist Sir Charles Villiers Stanford (1852-1924), is today best known for his choral works and as teacher to some of Britain's most successful composers of the twentieth century. Stanford was a prolific composer of numerous genres of music, and his chamber works for strings comprise a significant portion of his total compositional output. A great many of Stanford's chamber compositions were never published and are absent among today's standard chamber music repertoire. Until now, Stanford's String Quartet No. 4 in G minor, Op. 99 has never been published. This project comprises the first published edition of the String Quartet No. 4, making the work more readily available to performers and scholars. The String Quartet No. 4 is the last of Stanford's string quartets to be published, and this project makes the publication of his works in this genre complete. The author hopes that this project will help generate interest in Stanford as an important figure in British music history and bring his works to a greater public awareness through performance and study.
