Starting at the left, let the first bar be 1 unit high.
The second bar is 2 units high.
The third bar is 4 units high.
The fourth bar is 9 units high.
The fifth bar is 15 units high.
The sixth bar is 20 units high.
The seventh bar is 19 units high.
The eighth bar is 15 units high.
The ninth bar is 9 units high.
The tenth bar is 4 units high.
The eleventh bar is 2 units high.
The twelfth bar is 1 unit high.
