The Planets is a seven-movement orchestral suite by the English composer Gustav Holst.
The concept of the work is astrological rather than astronomical (which is why Earth is not included): each movement is intended to convey ideas and emotions associated with the influence of the planets on the psyche, not the Roman deities.

This is an arrangment of the main theme of the 'Jupiter' movement, "The Bringer of Jolity". But it is also well know as an British hymn, "I vow to thee, my county"
