Form

Part of The Elements of Art

Students will be introduced to one of the basic elements of art—form—by analyzing the types of forms and materials used in various sculptures. Students will then experiment with line in both two and three dimensions to see how shapes become forms.

This sculpture is made up of ten shapes connected with rigid, straight brown wire to create an interlocking, web-like formation that rests on the floor. Five of the shapes appear to be raw wood and the other five are painted. Four of the painted shapes are dark gray. The fifth painted piece, at the upper left in this photograph, has a wooden cone-shaped tip pointing downward beneath a black and white mid-section, and an angular, hourglass-shaped tail painted in triangular blocks of red, blue, and black. The other wooden and painted shapes range in size and form, with an almond-shaped piece at the center, rounded pieces throughout, and two rounded hour-glass shaped pieces near the upper left.

Warm-Up Questions

What do the forms on this sculpture remind you of? Can you find geometric shapes? Do some of the forms look like things in nature?

Background

Imagine using an air pump to inflate flat shapes. What do you get? Form! Forms are shapes in three dimensions:

Circle —> Sphere
Square —> Cube
Rectangle —> Rectangular prism
Triangle —> Pyramid

These are geometric forms, which are precise and regular. Have students feel the forms of various objects that are spheres, cubes, and pyramids. They are often found in human-made things, like buildings and machines while biomorphic shapes are found in nature. These shapes may look like leaves, flowers, clouds—things that grow, flow, and move. The term biomorphic means: life-form (bio=life and morph= form). Biomorphic shapes are often rounded and irregular, and can also turn into forms. Sculpture is the most obvious place to see form, or three-dimensional shape, in art.

This work of art by Alexander Calder includes both geometric and biomorphic forms. His training as an engineer was important to his working method. Known for carrying a pair of pliers with him at all times, Calder’s first contribution to modern sculpture was working exclusively in wire during the 1920s. Early sculptures, which have been described as three-dimensional drawings, were mainly portraits of friends and depictions of animals or circus characters.

Alexander Calder invented mobiles—sculptures that moved—in the early 1930s. During World War II, Calder created the Constellations series. The pieces are motionless, called stabiles, yet airy, like mobiles. Many, for example Vertical Constellation with Bomb, rest on a flat surface, but some Constellations are mounted from the wall at an angle. Generally, they are composed of small abstract forms carved from wood that are carefully arranged in three dimensions. The materials are either painted or left unfinished. Vertical Constellation with Bomb is one of the more complex works in the series, combining forms of varying sizes that define broader three-dimensional space than other Constellations. On the periphery, smaller forms reach out, suggesting movement into further horizons. There are five bare wooden forms and five painted forms, four of which are black. The wires are painted red.

Guided Practice

View the slideshow below to have students describe the forms they see by answering the following questions for each sculpture:

  • Are the forms geometric or biomorphic? Or both?
  • What do you think the sculpture is made of? Metal, stone, wood, plastic, clay, marble, or something else?
  • Do you think it’s made out of a single piece or multiple ones? If multiple, how would you attach them together? (If you look closely at Martin Puryear’s Lever No. 3, you will discover seams of laminated strips of pine, which the artist planed, sanded, and painted black. In many places, the bare wood shows through, giving the sculpture a distinctly handmade look. Puryear is an ardent craftsperson, who studied woodworking techniques as part of his artistic training.)
  • If the work of art is abstract, what does the sculpture remind you of? Something man-made or in nature?

Slideshow: Form in Works of Art

This free-standing sculpture is made up of panels and geometric shapes of vivid yellow, crimson red, white, and slate gray, all outlined with bold, jet-black lines, to create a simplified, cartoon-like, single-story house. The sculpture sits slightly off the ground on four metal feet, and is displayed on a grassy lawn with an iron fence and trees in the background. One short end of the house faces us, to our left. The peaked wall is white and is pierced with a window divided into six empty panes, two across and three down, and flanked by red shutters. Above the window is a tall, rectangular air vent with six horizontal slats. Below the window a loose grid of three horizontal lines and four short, vertical lines suggest an abstracted brick pattern. The long side of the house moves away from us to our right. It has a red chimney at the center of the gray roof. The wall of the front of the house is canary yellow. There is a white door at the middle and two more six-paned windows with red shutters to each side. Two shallow white steps leading down from the door are suggested by staggered, narrow rectangles. A dove-gray band runs along the bottom of both walls. All of the features, including the windows, shutters, door, chimney, roof, and gray band are outlined in black.

Activity

While studying at the Art Students League in New York, Alexander Calder developed a talent for continuous line drawing: creating an image with one single, unbroken line. He further honed his skills as a draftsman while working for several newspapers in New York City. Calder’s exploration of line moved into three dimensions when he began to create sculptures made of wire, like Rearing Stallion (right), a material that he had loved since he was a boy.

Students will experiment with line in both two and three dimensions to see how shapes become forms:

  1. Students will choose a subject they can closely observe: a fellow classmate, a flower, an object in the classroom, or—like Calder—an animal.
  2. Before picking up their pencil, guide them to let their eyes wander over the edges of their subject. Alternatively, students can follow the edges of their chosen objects with their fingers to get a sense of overall form.
  3. Next, using their index finger, students should trace the outlines of the subject in the air and then on their paper. As an alternative to accommodate visual impairments, students would be given a glue bottle to draw with on paper.
  4. Finally, students will use their pencil or pen to begin to draw, working slowly without lifting the pencil until the whole picture is finished. The continuous line can cross over itself and loop from one area to another until the single line has drawn the entire subject. Continuous line drawings take practice, so they may need to explore different strategies by making several drawings of the same subject. As an alternative to accommodate visual impairments, students would use lengths of yarn to place over the glue outline to create a raised surface drawing.
  5. Now try it in wire! Think of wire as a single continuous line. Demonstrate how to carefully bend and twist a single length of thin wire to create a three-dimensional “drawing.” Students will then recreate their line drawing in wire.

Extension

Exhibit the sculptures next to the line drawings for class discussion. (To display the wire sculptures, they can either be stuck into a lump of clay or be hung up with string.) Student artists should each answer the following questions about their process:

  • What was challenging about making a continuous line drawing?
  • What was different about making the sculpture?
  • What did you learn from trying both?

Painted with small areas of mostly flat color, this horizontal painting shows three brown-skinned people in the room of a home with pale gray walls and wood floors. To our right, a woman wears slate-gray skirt, a white apron and shawl, and a red headscarf with black and white polka dots. She sits in a black wooden chair facing our right in profile, smoking a pipe. A steaming kettle and bright green coffee pot sit on a black wood stove behind and to the right of the woman, with firewood stacked to the right. A clock or timer and an oil lamp sit on a red shelf above the stove and the woman’s head. Beneath her feet is one of three rectangular area rugs with a pattern of green, black, white, and red stripes. A window at the center of the back wall of the room is mostly covered by a dark green curtain. The panes along the bottom are black and lined with white, suggesting snow or frost. A bucket and pewter-colored, shallow bowl sit on a bench on the second striped rug under the window. To our left, a small person standing on the third patterned rug wears short black pants, stockings, and suspenders over a white shirt. That person turns away from us and rests elbows near a lit candle on a table with a red and gray checkered tablecloth. The third person, possibly a young girl, sits on a blanket or a fourth rug patterned with yellow, red, black, and green triangles. That young girl wears a gray dress and black shoes. She cradles a baby doll, and a white dog, perhaps a stuffed animal, sits next to her. A few cracks in the wall near the window expose horizontal bands, perhaps narrow wooden boards under damaged plaster. The artist signed the work with black letters in the lower right corner: “H. PiPPiN.”

Educational Resource:  Horace Pippin's Story, Grade Level: 1–2

Students will learn about the life and painting style of African-American artist Horace Pippin. They will discover how to "read" the clues in his painting School Studies and write a story about the work. By solving counting and time problems, students will also create their own "secret number" painting.

We look across a wide, low clearing at a mountain rising beyond rocky hills, which are mostly covered in pines and blazing red and orange autumn trees, in this horizontal landscape painting. The green grass of the clearing is littered with dead trees and stumps. Beyond a narrow opening between the hills, almost at the center of the composition, a massive mountain towers against the powder-blue sky, nearly reaching the top edge of the painting. The mountain’s jagged face is mottled with warm tones of cinnamon, rust, and caramel brown. The scene is bathed in warm light coming from our right but pewter-gray storm clouds move in from the upper left to encircle the mountain peak. Closest to us, a line of broken tree trunks spans the width of the painting, mixed with scarlet-red, marigold-orange, and green vegetation and reeds. A silvery pond lies just beyond them to our left. Tiny in scale within the landscape, a horse and rider gallop along a wide dirt road emerging from the lower right toward a white house nestled at the foot of the hill to our left. The rider wears a knee-length, denim-blue tunic and red leggings. Upon closer inspection, two children and a white dog become visible, walking toward the rider. A straw-yellow structure sits against the hill to our right. A horse-drawn carriage moves away from the house in the far distance, where the road curves toward the notch. The artist signed and dated the painting as if he wrote directly onto a broken trunk in the lower left corner of the painting: “T. Cole 1839.”
