From NYTimes.com: In Sister’s Book and Father’s Scrawl, Music Thought to Be Mozart’s

Since the 1760s, the fragmentary works sat scrawled at the back of a music book used by Mozart’s sister to study keyboard. They were in the hand of their father Leopold, but no composer’s name was attached.

Mr. Leisinger said in a telephone interview that the pieces were most likely composed in 1763 or 1764, when Mozart was 7 or 8. If truly by him, they would serve as an important link between his simple earliest compositions and his first major works, Mr. Leisinger said.

Listening to the music, it seems impossible that it was written or even played by a 7 or 8 year old.  But, I have never been in the presence of genius like Mozart.
