Earlier today, two newly-discovered piano pieces by Mozart were performed in Salzburg. It is believed he wrote them at the age of 7 or 8.
Research by the International Mozarteum Foundation revealed that the works, previously thought to be anonymous, were in the writing of Mozart's father Leopold. However the compositional style and the number of technical mistakes suggest that Leopold was merely transcribing the noodlings of his gifted son.
Sadly (and predictably) they're not anything special, but it's still fascinating to see what a prodigy could turn out at an age when most kids are still struggling with their C-major scales.
