This is a special kind of music. 
A man named Gustav Holst wrote special music. 
Gustav Holst was a famous English composer. 

He used a very large orchestra. This helped him make many different sounds. The music uses woodwinds, brass, and percussion. It also uses harps and strings. In the part called "Neptune, the Mystic," a group of women sings. They sing without using any words.
Holst worked on the music for nearly three years. He had a busy job at a school. His arm also caused him pain. Two friends helped him write the notes. The music first played in London in 1918. Some critics did not like the new sounds at first. Now, the music is loved all over the world. It has been recorded at least 80 times.
*The Planets*, Op. 32, is a famous orchestral suite by the English composer Gustav Holst. 
To create these sounds, Holst used a very large orchestra.
Holst began working on this music in 1914. He finished the orchestration in 1917. Writing the music was a slow task for him. He had a very busy job at two different schools. He also suffered from a painful condition in his right arm called neuritis. Because of this, he had help from two colleagues named Vally Lasker and Nora Day. They acted as his scribes to help write the 198 pages of music. He mostly worked on the suite during his holidays and weekends.
*The Planets* had its first performance on 29 September 1918. 
Each movement in the suite has its own unique musical personality. For example, "Mars, the Bringer of War" uses a relentless rhythm. It can sound very violent and even terrifying to some listeners. In contrast, "Venus, the Bringer of Peace" is much more tranquil. It uses gentle sounds from the flutes and harps. The movement "Mercury, the Winged Messenger" is very fast and short. It is the shortest part of the suite, lasting only a few minutes. These different styles show how Holst could turn ideas into many different sounds.
*The Planets*, Op. 32, is a monumental seven-movement orchestral suite composed by the English composer Gustav Holst. 
To achieve these varied moods, Holst employed a very large orchestra to provide diverse tone colors.
The composition process was a long and difficult journey for Holst. He began the work in 1914 and finished the orchestration in 1917. Because he held demanding positions at St Paul's Girls' School and Morley College, he could only compose during weekends and holidays. Additionally, Holst suffered from chronic neuritis in his right arm. This condition made writing the 198 pages of the full score very challenging. He relied on two colleagues, Vally Lasker and Nora Day, to act as his scribes. They helped him transcribe the music that his hand could not easily manage.
The origins of the suite trace back to a 1913 holiday in Spain. While traveling with Balfour Gardiner, Arnold Bax, and Clifford Bax, Holst became interested in astrology. He studied the subject closely, even reading Alan Leo's booklet, *What Is a Horoscope?*. This interest influenced the titles of several movements, such as "Mercury, the Winged Messenger" and "Neptune, the Mystic." While astrology provided the initial spark, Holst ultimately arranged the movements to maximize dramatic impact. For instance, he chose to open with "Mars" instead of "Mercury" to create a more compelling musical beginning.
The premiere took place on 29 September 1918, at the Queen's Hall in London. 
Each movement offers a distinct musical experience. "Mars, the Bringer of War" is defined by a relentless ostinato and intense rhythmic experiments.
Other movements continue this exploration of character and scale. "Jupiter, the Bringer of Jollity" uses the orchestra to portray an abundance of life and vitality.
