Hal Leonard Corp. is the world’s leading publisher of sheet music and music-educational books (think Hal Leonard Guitar Method), churning out 50,000 new pages of sheet music each year through deals covering a dizzying collection of artists, from Hendrix to Gershwin to all things Disney. Music from Frozen sells so well that Hal Leonard has sliced and diced it many different ways, as choral, solo and string arrangements.
The office is a cubicle maze filled with instruments and keyboards played by editors who arrange music, later laid out and given a memorable cover by graphic designers. It all happens within the same building, often within the same day.
In 1985, Mardak and several other managers bought Hal Leonard from the three original founders. Thus began a career in both consolidating the sheet music business and collecting cool stories.
One of them: Turns out, not all stars can read music. When Hal Leonard first presented U2 with their own sheet music, the legendary Irish rockers were taken aback, Mardak says. “They looked at it, and they said, ‘This is what I play right here?’” Other artists, however, want to review and approve every note.
“We’re basically the archivists for the music industry.”
— Brad Smith, Hal Leonard Corp. vice president of musical instrument products

Just now beginning to wind down his career, Mardak sold the company in 2016 to a private equity firm, Seidler Equity Partners, for an undisclosed amount. He remains chairman and CEO, describing Seidler as a “holder” outfit, not a flipper looking to turn a quick buck.
Personal struggles have also encouraged Mardak to slow down: In 2014, he tripped and fell into a burning fireplace at his winter house in Phoenix, suffering third- and fourth-degree burns to his neck and face. He has undergone more than 30 reconstructive operations and could yet have another. In more recent days, knee and shoulder surgeries have sidelined him from what had been a dedicated amateur handball career. He was known for his devastating “Mardak serve,” a deceptively lazy lob that boggled opponents used to more aggressive strikes.
But in business, the beat goes on. In April, Hal Leonard bought its largest counterpart in Europe, The Music Sales Group, in a $50-some million deal that included 11 music shops it now hopes to spin off. “We’re not overly thrilled about being in the retail business,” says Mardak. “We’re looking for someone who would be interested in them.”
Hal Leonard is, at its core, a publisher. “We’re basically the archivists for the music industry,” says Brad Smith, vice president of musical instrument products and brother of Red Hot Chili Peppers drummer Chad Smith. (He insists he taught his famous brother to play.) He pulls out a slick Hal Leonard hardcover book on Fender guitar amps, with an introduction by Keith Richards. “It’s really cool,” he says.
