Here’s one busker whose instrument can’t fit on the subway.

Classically trained Kevin Shoemaker rolls his 500-pound J&C antique upright piano around the streets of Manhattan looking for a sidewalk to play on.

“It’s very heavy,” said the 23-year-old Washington Heights resident. “I have a piano dolly, it’s like a furniture dolly but it’s made for a piano. It sits underneath it and helps it move.

“I just have to make sure I don’t hit a pothole or that the street isn’t sloping down or that I run into a car.”

The sight of Shoemaker pushing his piano bemuses even the most jaded New Yorkers.

“Drivers are very patient with me when they see me moving my piano across the street, even if I’m crossing against the light,” said Shoemaker. “Some of them even yell out positive stuff like ‘Keep pushing man,’ or ‘you’re my hero.’ So many people take my picture I don’t even pay attention anymore. I guess it’s not a sight they see everyday.”

The aspiring classical composer, who occasionally plays in a hip-hop band, has an eclectic playlist: from jazz tunes and Chopin, to Gershwin and Kanye West. He started playing the piano as a 6-year-old.

He generally rakes in about $30 to $40 an hour, and plays for about four hours, three or four times a week.

“The biggest tip I ever got was in Washington Square Park,” Shoemaker recalled. “I was playing under the arch and I was getting ready to pack up but these two older ladies came over so I thought I’d play a few more songs for them. They ended up giving me $20 dollars each. That made my day.”

His favorite spot is Christopher Street and Bleecker. “It’s not the biggest of intersections,” he said. “It’s a nice mix of people and a lot of foot traffic. It’s an intimate atmosphere. I seem to make a connection with the people there. I don’t know if it’s because the people who hang out in the West Village are different, but they seem to appreciate it a little more.”

The piano man stores his instrument on Spring Street, splitting the $200 rent for the storage space with another musician.

He does most of his paid professional work during the academic year, so from June to August he heads outdoors to busk.

“A lot of choirs will do their seasons from September to May,” he explained. “So the summer months can get a little lean and I’m always looking for ways to make extra money in between the more formal gigs I do.”

“I can’t imagine living life if I wasn’t doing music,” he said.
