Jerusalem (413.11.optional Perc.) Sir Charles Hubert Hastings Parry (1848-1918) was an English composer, teacher and historian of music. As a composer he is best known for "Jerusalem", the coronation anthem "I was glad" and the orchestral and choral ode “Blest Pair of Sirens”, his orchestral works include five symphonies and a set of Symphonic Variations. Parry was taken up by George Grove, first as a contributor to Groves massive Dictionary of Music and Musicians in the 1870s and 80s, and then in 1883 as professor of composition and musical history at the Royal College of Music, of which Grove was the first head. In 1895 Parry succeeded Grove as head of the College, remaining in the post for the rest of his life. Parrys influence on later composers is widely recognised. Edward Elgar learned much of his craft from Parrys articles in Groves Dictionary, and among those who studied under Parry at the Royal College were Ralph Vaughan Williams, Gustav Holst, Frank Bridge and John Ireland.
