The challenge was to have 88 different pianists simultaneously play an acoustic piano. This would be a world record that could never be broken (pianos have 88 notes*). How was it done?
Twenty or so people can position themselves close enough to a piano’s keyboard to be able to play it, but 88? The only way to get this number of people around a piano is to position them several yards away, and then use some kind of finger extenders!

The project, aptly titled 88 Pianists, was created by Professor Julian Allwood at the University of Cambridge Department of Engineering. And it was solved by inviting 2,500 primary school children aged between 7 and 10 to design 88 different mechanical fingers. 35 primary schools from across the UK were involved.
Pupils spent the last 12 months coming up with ideas. And these were subsequently built with the aid of various university engineering departments.
88 Mechanical Fingers
The mechanisms are quite amazing. They are all different, some up to seven meters long, and by necessity very thin. They include flying rabbits, giraffes, ballerinas and much more. Each “finger” has a name. These include, “The Mechanical See Saw Beanstalk“, “Banana Gun“, “Magnificent Mermaid Mechanism“, “The Bike Wacker“, “The Triple Wrecking Ball“, and there are 83 more here.
There is one additional mechanism “The Tubalicious Invention“. This remotely activate the sustain pedal by means of hydraulics and a set of blue ping-pong balls.
To break the world record, which previously stood at 30, the 88 pianists took part in a special concert at the opening of the General Assembly of the International Academy of Production Engineering (CIRP) at the ICC Birmingham on August 19th, 2019.
Celebrating Leonardo da Vinci’s 500th
The various mechanical fingers were attached to a Steinway Model D Grand Piano. The ensemble played a piece called “Leomortal” by composer and keyboardist Martin Riley in front of over 500 leading engineers.
The project had originally been conceived to commemorate the 500th anniversary of the passing of Leonardo da Vinci. It was
“This was a truly fantastic collaboration between engineering and music! The imagination of the children involved was astonishing and has to be seen to be believed. Royal Birmingham Conservatoire is so proud to have collaborated with ten UK Universities on this world record-breaking project which yet again proves music’s power to inspire children.”
Professor Julian Lloyd Webber, Principal of the Royal Birmingham Conservatoire (part of Birmingham City University).
