Chapman, a leading trainer in the north for decades, died in 2011 and the race has been run in his honour ever since.
Renowned for his training of such classy sprinters as Chaplins Club and Soba, he would be proud of Carr's achievements with the eight-year-old.
Runner-up in the Great St Wilfrid last season, Pipers Note (11/4) was winning at the track for the seventh time and the result never really looked in doubt under Jack Garrity,
"It's fantastic. He's a lovely old horse who really enjoys it here. It's all come right on the day for once," said Carr.
"In the past we've tried to buy one for this and we've come close before. We've had this lad a couple of years now since his owners decided he needed a change of scenery.
"Before today he's been rated too high to get into the race, but he's not been in the same form this season, dropped in the weights a bit and that meant he could get in.
"He was second in the Great St Wilfrid last year to a Group horse who'd been retired to stud once (Mattmu), so we felt a bit hard done by. We'll have another go next month."
Tim Easterby's Midnight Malibu is a multiple winner but was scoring for the first time at Ripon in the Ripon Cathedral Fillies' Handicap.
Sent off the 6/4 favourite down in grade, she made nearly all the running for Jamie Gormley.
"It really helps that you can run horses from 1lb higher than the weight band. She's rated 86 and this was a 0-85, but up in grade she struggles a bit," said Easterby.
"She has a cracking attitude and has won plenty."
The Michael Dods-trained Bartle Hall attracted late money from 33/1 into 16s to make a winning debut in the Ripon Museums Maiden Stakes.
Favourite Three Card Trick looked sure to win entering the final furlong, but Connor Beasley's mount quickened up impressively.
"They went a good gallop early and she was a bit unbalanced on the ridges," said Beasley.
"Once she hit the level ground inside the final furlong, she really put her head down. It looked a good race on paper beforehand."
David O'Meara's Mutadaffeq (11/8 favourite) was not winning out of turn in the Fountains Abbey World Heritage Site Handicap.
Placed on his last three starts, Jim Crowley drove him home to win by three-quarters of a length.
"He deserved that. He stayed on nicely and might get further. Jim said they went a muddling gallop early on," said O'Meara.
O'Meara's Mayson Mac was narrowly denied by James Tate's Implicit (9/4 favourite) in the Newby Hall And Gardens Nursery Handicap.
Winning jockey Tom Eaves said: "He did it well really because he didn't handle the track, not many youngsters do here, to be fair."
William Haggas has a better than 25 per cent strike-rate at Ripon and sent Snow Wind (evens favourite) from his Newmarket base to win the Lightwater Valley Novice Stakes in some style for PJ McDonald.
