"I was so amazed. Here is this exquisite old grand piano nearly 150 years old sitting in a hotel in Wanganui.
"It was so unexpected, because it's the kind of fine old instrument you'd expect to find in a museum, not a hotel."
Mr Greenfield, who described Brinmead as a prolific piano maker, had been visiting the hotel as part of his check of three local venues the opera students were singing at last week.
"I question the piano being in a hotel; I really do."
But Mr Gorrie said he thinks the placement of the beautiful old piano is perfect.
"I spent a long time looking for an antique grand piano for my hotel. I finally, after a lot of searching, found this one on Trade Me."
The piano came from "somewhere near Auckland" and cost $5000, he said.
"I really love it and think it looks wonderful, so it's staying right here."
