It's hard to pick a favourite Beethoven piano sonata. There's No.8, the 'Pathétique'. Or No. 23, 'Appassionata'. But perhaps out of all of them, the finest - and certainly most famous - is No. 14: the 'Moonlight' sonata for piano and pink balloon.
Yes, pink balloon. Not the most common of instruments to use at the turn of the 19th century, we'll grant you. But a very beautiful one with an aching, melancholic tone.
Just click play on this video above - which stars American musician David Hull on pink balloon, accompanied by Denis Pankov on piano - to see what we mean.
It's very wonderful, very skilful and very, very silly indeed. And it's just the sort of thing we want to see on this year's 'Britain's Got Talent'.
