12-year-old composer Alma Deutscher improvised a beautiful sonata from 4 musical notes drawn from a hat.
From Open Culture:
"At age six she composed her first piano sonata. At age seven, she completed her first major composition, the opera The Sweeper of Dreams. Aged nine, she wrote a concerto for violin and orchestra, which she premiered in a 2015 performance." And at "the age of ten she completed her first full-length opera, Cinderella, which had its European premiere in Vienna on 29 December 2016 under the patronage of conductor Zubin Mehta." Fast forward to age twelve, you can watch Alma pull off something that, at this point, shouldn't come as a surprise. Above, 6o Minutes correspondent Bob Pelley pulls four random notes out of a hat. Then, soon enough, Deutscher uses the notes to start improving a sonata. Watch more of her performances on her YouTube channel.
