The Planets in the context of "Queen's Hall"

Vocal music is a type of singing performed by one or more singers, either with instrumental accompaniment or without instrumental accompaniment (a cappella), in which singing provides the main focus of the piece. Music which employs singing but does not feature it prominently is generally considered to be instrumental music (e.g. the wordless women's choir in the final movement of Holst's symphonic work The Planets) as is music without singing. Music without any non-vocal instrumental accompaniment is referred to as a cappella.

Vocal music typically features sung words called lyrics, although there are notable examples of vocal music that are performed using non-linguistic syllables, sounds, or noises, sometimes as musical onomatopoeia, such as jazz scat singing. A short piece of vocal music with lyrics is broadly termed a song, although in different styles of music, it may be called an aria or hymn.

Gustav Holst (born Gustavus Theodore von Holst; 21 September 1874 – 25 May 1934) 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. Among other teaching activities he built up a strong tradition of performance at Morley College, where he served as musical director from 1907 until 1924, and pioneered music education for women at St Paul's Girls' School, where he taught from 1905 until his death in 1934. He was the founder of a series of Whitsun music festivals, which ran from 1916 for the remainder of his life.
