Together, they have been selected as one of 16 contestants for this open competition, which accepts musicians up to 25 years old and features a number of university performance piano students.
Delvan won the Wallace Junior National Piano Competition last year, but the Wallace National Piano Competition is a much harder competition.
The competition runs from Thursday, 2 till Sunday, 5 July with two preliminary rounds and a grand final.
