The 10-year-old earned the right to play at the prestigious venue after winning the American Protégé International Music Talent competition.
Caelan was the only Australian to perform at the Boxing Day concert, joining representatives from Canada, Bulgaria, Costa Rica, China, Thailand, Korea, Singapore and the US.
The Mt Pleasant resident has been playing piano since age five and is taught by his mother Helene.
“It was an amazing experience playing at Carnegie,” he said.
“I felt very honoured and excited but also a little nervous.”
Caelan is well known in Perth, having won numerous prizes and trophies for piano at music eisteddfods, festivals and competitions – including the coveted Most Outstanding Junior Pianist award at the Fremantle Eisteddfod which he has won two years running.
An All Saints College student, Caelan also plays cello and regularly performs in school ensembles and music groups.
He also enjoys composing on piano and hopes to one day return to Carnegie Hall to perform one of his own original pieces.
