John Crosskey’s iconic piano was designed by the pianist in the iconic role of gabriella Monteros piano in the 1962 film, The Wizard of Oz.
It has been on the cover of the film since 1973.
A number of other famous pianists have used it.
It is currently on display at the Australian National Museum in Canberra.
“It is quite a bit of work, and it takes a lot of time,” Ms Monterosa told News.co.uk.
“So when you have a piano you have to work on the way it is going to be played, so that the keys are in a good place, that the fingerboard is in a decent place, and that the sound is going through the piano as if it is a real instrument.”
And then you have the other little pieces that come in, and those little bits of sound, and all those little things add up.
“I think when you get a piano that is so good that it is almost as good as a real piano, it’s almost a miracle that it was not stolen or broken.”
Ms Monerosa said it was important for people to realise the work of artists like John Crosskeys to remember.
“There are many famous pianos that we don’t know about, like John’s piano,” she said.
He is one of the most significant people in the world of music.”
