The official duties of Master of the Royal Music are few  -- they normally writes the occasional small work to commemorate a Royal occasion. 

He was born the son of Thomas Parratt, organist of the parish church in Huddersfield, a post he had held from the age of 19, and in which he was to be succeeded by Henry his elder son.

At the age of eleven Walter became the organist at Armitage Bridge church and was of such stature that he rose to St. George's chapel, Windsor. He was knighted in 1892.
