If the redevelopment of the Steinway & Sons piano store in Midtown were a song, it would be a long one, with some dramatic pauses and a bit of dissonance.

But despite the project’s yearslong struggles with escalating costs, infighting and lawsuits, the developers of the sky-high condo at 111 West 57th Street hope the building will still impress potential buyers.

“As my grandmother said: ‘Good food takes time,’ ” said Michael Stern, the managing partner at JDS Development Group. The firm has teamed up with Property Markets Group and Spruce Capital Partners on the condo, which is the latest to elbow into the elite group of high-rises along Billionaires’ Row.

The 60-unit tower, which overlooks Central Park near Avenue of the Americas, has certainly tried to stand out in a crowd. At 1,428 feet (or 86 stories), 111 West 57th will be one of New York’s tallest buildings when it’s completed in 2019. By contrast, the office tower One World Trade Center, the city’s loftiest spire, is 1,776 feet, while 432 Park Avenue, a new condo tower nearby, measures 1,396 feet, and One57, at 157 West 57th Street, is 1,004 feet.
