The Opera Australia baritone will take part in a dressage display and sing the New Zealand national anthem at the event.
Arthur grew up on the Taieri and was an accomplished sportsman, representing New Zealand at showjumping and Otago at rugby and basketball.
He became a professional singer when a knee injury ended his playing career and now lives in Sydney.
''Jud Arthur's involvement has added an extra dimension to the programme, which has shaped up to be a really exciting equestrian event for the public,'' Ross Farquhar, of Otago Show Jumping, said.
''The major features are punctuated by cowboy and trick riding, which will be great family entertainment, and then it's topped off with the Abba show Bjorn Again.''
Ride the Rhythm opens at 2pm at Forsyth Barr Stadium on February 1.
