Gustav Theodore Holst was an English composer, arranger and teacher. Best known for his orchestral suite The Planets, he composed many other works across a range of genres, although none achieved comparable success. His distinctive compositional style was the product of many influences, Richard Wagner and Richard Strauss being most crucial early in his development. The subsequent inspiration of the English folksong revival of the early 20th century, and the example of such rising modern composers as Maurice Ravel, led Holst to develop and refine an individual style.
There were professional musicians in the previous three generations of Holst's family, and it was clear from his early years that he would follow the same calling. He hoped to become a pianist, but was prevented by neuritis in his right arm. Despite his father's reservations, he pursued a career as a composer, studying at the Royal College of Music under Charles Villiers Stanford. Unable to support himself by his compositions, he played the trombone professionally and later became a teacher-a great one, according to his colleague Ralph Vaughan Williams.
