Bryce Dudal may work as a pizza delivery driver during the day, but that doesn't mean that he doesn't have some incredible talents hidden up his sleeve.

The Varchetti family was treated to a stunning pre-dinner performance earlier this week when they ordered pizza from Hungry Howie's to their sub-suburban Detroit home in Michigan.

The 18-year-old delivery guy handed over the pepperoni pie, noticed the family's unused grand piano inside their foyer, and asked if he could play something.

Dudal then proceeded to play Beethoven's third movement of "Moonlight Sonata".

Astonished by the youngster's skill, the Varchettis took a video of the performance and posted it to Facebook where it has been viewed thousands of times. The Varchetti's son even stopped playing video games so he could listen to the song.

The most impressive part? Dudal says that he is mostly self-taught.

He started playing piano on his family's keyboard when he was 6 years old. He learned to play several simple TV show theme songs and children's tunes until finally, his mom bought him some Beethoven CDs – one of which was "Moonlight Sonata". Entranced by the third movement's intensity, he started learning the piece by ear, with some help from YouTube videos. Within a year, he had it nailed.

"It was a long process. You have to sit there and think and try to put it on the piano, piece by piece. I couldn't read music back then," he told The Washington Post. "I would sit there and listen for hours and hours and try to figure it out."

After going through several piano teachers who only wanted to teach him the basics, he finally found a teacher who appreciated his zealous style of learning at 12 years old. He recently took a break from playing piano so he could focus on playing baseball, but his performance for the Varchettis has renewed his love for the instrument – especially after receiving an outpouring of praise from the video's Facebook comments.
