We put portraits of the great composers through Microsoft's 'How Old Do I Look?' tool. Here's what it came up with…

Can a computer tell how old the great composers are in their portraits? We put Microsoft's new tool to the test…

1. How old is Beethoven?

This sweet little portrait of Beethoven was actually painted when he was 13. Oh and he's not a girl. Nice one, Microsoft.
2. How old is Liszt?

He was actually 75 here… looking good, Liszt! Picture: Getty
3. How old is Shostakovich?

Microsoft shaves a few years off Shostakovich's actual age – he was 65 in this photo. Picture: Getty
4. How old is Bernstein?

The tool adds ten years to poor Bernstein's real age here – he was 44. Picture: Getty
5. How old is Handel?

Handel clearly hasn't been moisturising enough – he's actually 41 in this portrait.
6. How old is Vivaldi?

Try subtracting 20 from that, Microsoft… the composer of The Four Seasons was actually 30 here. And a man. Whoops, computer!
7. How old is Clara Schumann?

Not bad, internet. The leading virtuoso pianist of her day was actually about 21 when this portrait was done.
8. How old is Mozart?

So Mozart was seven when this portrait was painted. And 'How Old Do I Look?' has him pegged for a 20-year-old woman. Right.
9. How old is Mendelssohn?

But pity poor Mendelssohn. He's the tender age of 12 in this picture and this website thinks he's a 43-year-old woman. Maybe it's the hair?
10. How old is Bach?

Bach clearly had a mean skin-care routine – he's actually 61 here.
11. How old is Monteverdi?

Computer says 'no' for Monteverdi. "Couldn't detect any faces" :(
12. How old is Rachmaninov?

Almost spot-on! Have a gold star, computer. Rachmaninov is 64 here. Picture: Getty
13. How old were Brahms and Johann Strauss II here?

Johann Strauss II definitely gets the better deal here – he was actually 66 here. Brahms, however was a comparative spring chicken – just 58. We blame the beard. Picture: Getty
