The piano that featured on many of ABBA’s greatest hits is going under the hammer next month in London, auctioneers Sotheby’s said.
The piano is estimated to fetch between £600,000 (R12.1-million) and £800,000 when it goes on sale on September 29.
Swedish pop foursome ABBA dominated the 1970s disco scene.
“The opening piano glissando from Dancing Queen is one of the most distinctive sounds of the 1970s and we are delighted to offer the actual instrument used by the legendary ABBA in their major recordings,” said Sotheby’s expert Philip W Errington.
“The piano itself is an instrument of real importance and with the added ABBA provenance we expect it will have worldwide appeal.”
It was built by Swedish musical instrument designer Georg Bolin for the US jazz pianist Bill Evans.
The New York Times described it in 1964 as a “space-age piano”.
It was bought by Stockholm’s Metronome Studios in 1967 and appeared on nearly all of ABBA’s recordings between 1973 and 1977.
“The Bolin Grand is one of a kind and was a great source of inspiration while working in the recording studio during the ABBA sessions,” said the group’s pianist Benny Andersson.
ABBA disbanded in 1983.
Famous pianos have earned huge sums at previous auctions.
In 2000, John Lennon’s Steinway upright piano, on which he composed Imagine, was bought for £1.67-million by the singer George Michael. The upright piano which featured in Rick’s Café Americain in the 1942 film Casablanca was sold in 2014 for $3.4-million (R44.6-million).
