A "Three Musicians" (Pablo Picasso, 1921)
This
colourful picture shows three musicians in old theatrical costumes. On
the left, there is a clarinet player wearing a white pierrot ['piarouj
suit (a pier- rot was a kind of clown), with a dog behind him. In the
middle is a guitarist dressed as a harlequin ['hcdikwin] (another kind
of clown). A singer in a monk's robe stands on the right. In many ways,
this is a confusing picture. The shapes overlap, so it is hard to tell
where one thing stops and another starts. The space looks strange, too.
The floor goes back further on the left than on the right, so the room
seems lopsided1.

B "Improvisation No. 26 (Rowing)" (Wassily Kandinsky, 1912)
At
first glance, фе painting doesn't seem to be a picture of anything in
particular. It just looks Tike a colourful pattern made up by the
artist. But in fact, it was loosely based on a view of two people in a
boat — as the second part of its title, Rowing, hints. If you look
closely, the picture contains clues about the scene which inspired it.
Can you make out a red curved line which might be a boat? Black lines
hint at two people sitting in it, rowing with long, dark oars. The boat
floats among dramatic splashes of colour, suggesting a wild watery
setting. Above, a dark, birdlike shape flies through an equally
colourful sky.
