Listening to Jericho play the piano, it's hard to believe he’s never had a lesson or learned to read sheet music.
Instead, the 13-year-old learns by ear, listening to a song, and then working out each note through trial and error - and plenty of practice!
Jericho jokes that his long fingers, a common feature of Marfan syndrome, which he lives with, might even make him a better pianist.
It's a talent he never expected to discover, and it all started at the Queensland Children's Hospital.
Born prematurely at just 28 weeks, Jericho has spent much of his life in hospital. At 4 years old, he was diagnosed with Marfan syndrome, a genetic condition that affects the body's connective tissue.
Because connective tissue is found throughout the body, the condition can affect the heart and blood vessels, bones and joints, eyes, skin and lungs.
Over the years, Jericho has had several surgeries, including operations on his eyes and, more recently, major surgery to correct severe scoliosis.
"Scoliosis is pretty common with Marfan syndrome and my back had a really big curve in it, so I needed surgery to straighten it," Jericho said.
"Before I could have the surgery, I had to wear a halo frame on my head for about three weeks to help stretch my spine.
"I had to stay in hospital the whole time. After a while, I got bored waiting for my surgery. That's when I found the piano."
Although he had never played before, Jericho sat down at one of the hospital's pianos (part of the arts in health program) and decided to teach himself.
"I'd never played piano before, but I just decided to learn."
What began as a way to pass the time quickly became something much more special.
"I started to really enjoy the piano. We had a keyboard at home that was collecting dust, so we brought it to hospital with me. I could play it in my room with headphones on," he said.
Marfan syndrome is a lifelong condition, so Jericho will continue to see his specialists at the Queensland Children's Hospital until he is an adult. But instead of dreading his appointments, he looks forward to them.
"I know going to hospital might seem like a bad thing for a lot of people, but I actually enjoy coming for my appointments because I know I'll get to play the piano."
The care and kindness Jericho has received have inspired another dream.
When he's old enough, he hopes to volunteer at the Queensland Children's Hospital to support other children going through their own health journeys.
"I just want to make people happy. When I was in hospital, the volunteers came to visit me and helped keep me entertained. I'd like to do that for other kids one day."
