He's one of classical music’s most important composers - and on the eve of his 80th birthday, we got to ask him what he thinks about the state of classical music in 2016.
The viola organista was dreamt up by Leonardo da Vinci but until recently it had never been built. Now, a Polish instrument-maker has painstakingly created the first ever example and it sounds remarkable
The instrument wasn't built during Leonardo da Vinci's lifetime and in fact it was only in 2013 that Polish instrument maker Sławomir Zubrzycki built the first-ever example.
The unusual instrument is a hybrid of elements from a harpsichord, an organ and a viola da gamba. It looks like a harpsichord and has a set of strings, but rather than being plucked, the strings press against rotating wheels covered in horse hair – the same mechanism that produces sound in string instruments.
Take a listen to Leonardo da Vinci's instrumental dream:
"I have no idea what Leonardo da Vinci might think of the instrument I’ve made, but I’d hope he’d be pleased," Zubrzycki said, at the instrument's unveiling concert in Krakow. He spent three years and more than 5000 hours bringing Da Vinci's instrument to life from his Codex Atlanticus, a 12-volume collection of his manuscripts and designs for everything from weaponry to flight.
As well as its unique sound (somewhere between an organ and a string instrument), the viola organista is ornately decorated with a Latin quote in gold leaf by Hildegard of Bingen, saying "Holy prophets and scholars immersed in the sea of arts both human and divine, dreamt up a multitude of instruments to delight the soul".
