Gustav Theodore Holst (21 September 1874 ? 25 May 1934)[1][2] was an English composer and was a music teacher for nearly 20 years. He is most famous for his orchestral suite The Planets.[1] Having studied at the Royal College of Music in London,[2] his early work was influenced by Ravel,[2]Grieg, Richard Strauss, and fellow student Ralph Vaughan Williams,[3] but most of his music is highly original, with influences from Hindu spiritualism and English folk tunes.[2] Holst's music is well known for unconventional use of metre and haunting melodies. Holst wrote almost 200 catalogued compositions, including operas, ballets, choral hymns, and songs (see Selected works below).
