N.B.:Harry Bertoia very seldom named his sculptures. For the sake of identification, this list is expanded from a catalogue of his work published by Allentown Art Museum in December 1975, accompanying the exhibit.

There are at least 17 major groups of sculptures that we can specifically describe, yet many of his
experimental work could be misattributed. There are also a few sculptors who have made derivative works.
Consult an qualified expert on Harry Bertoia.
Here are the types of sculpture :
The bushes were started in the late 50's and are made out of bronze. They vary in size from 8 inches
in diameter all the way to 6 feet in height. They are made by brazing bronze rods one by one to form a
tree structure, varying in density from sparse to incredibly thick.(some are so thick one can barely see
the center). After the structure is constructed, a bead of bronze, sometimes another tiny rod or melted
extremity, forms the end of the branch. The patina is mostly green, a few reds and a
couple are gold plated.

The Public Works are all across the US. One can find photographs and a list of locations on this site (Public Works). They vary in size from 5 feet to 45 feet. The materials that Harry used are very different from one to the other and as Harry evolved in time, so did his commissions.The first commission was General Motors Technical Center in 1953. It is 36 feet long,
the last one the Federal Reserve Bank of Richmond is a fountain that measures 18 feet by 10 feet
and was completed in 1978
Directly formed bronze or Extrusions were a happenstance. While Harry was cutting, brazing and working the metal, he noticed the spent rods, plates, pieces that were left. Some had "spacial" quality that were just waiting to be enhanced. Thus, when going to the scrapyards and metal wholesalers, he picked up possible candidates and enhanced them by polishing sufaces or brazing shots or melting, then mounting on a base. They are usually like little sketches that have a lot of scale. Some just have great sufaces of rugged and magmatic textures. The largest one that I know is about 14 inches.
Dandelions appeared first in 1961 in the Denver Hilton Hotel .They are build from a core which holds
thousands of rods. The Kodak pavillion of the New York Worl's Fair of 1964 had 7 dandelions around a
fountain. Pieces vary in diameter from 24 inches to 72 inches. The largest dandelion is in the Joslyn
Museum now on loan to the library and is 10 feet in diameter and 20 feet high. They are of usually of
stainless steel, some of them are tipped in gold. Because of their complexity, the are rare and were very
expensive to make even during Harry's lifetime.
Freeforms are exploration on using the bronze rods in a different way. Instead of using the linear
quality of the rod , Harry melted them part way and knotted them or just collapsed them on themselves.Thus creating very fluid anamorphic shapes that very much resemble aquatic plants. They seem to be moving in water. They are soundless and heavier in looks. Usually patinaed in green, the largest one we know of, is about 28 inches tall.
Gongs...are magic. They are earthy yet timeless. Their sounds move every fiber in one's body, some sounds so profound that our ears do not hear them but the body feels them. When one puts his ear near a gong that has been stuck, one can hear vibrations that are alike the creation of the universe, the "big bang".Usually very big, they are mostly made of silicone bronze. Some are hollow and look like warrier's shieldof old. The smallest we've seen is about 12 inches, the largest is on Harry bertoia's farm and measure almost 10 feet in diameter. Some have shapes cut out of them, looking like japanese crests. Most of those shapes were worked on paper in the monotypes(3: Other works)
Hanging bars are very "zen" like. They are an exercise in "being". Usually two rods are suspended from above and gently rotate. When touched, they harmonically sound. Made of beryllium copper for their sound quality, around one half inch in diameter and about 24 inches in lengh.
The sculptures made with rods and tubes were generally done for commissions. The smaller ones
were models or maquettes for large pieces. They are anamorphous and very flowing. A good example is the Marshall Universityfountain in Huntington, West Virginia
Harry was always looking to create new textures for his sculptures. Shot sculpture happened
when he had the idea to partially melt together the little shots of bronze the he received in boxes for
his castings. The result created a pebble look that he used in some small sculpture.
Multiplanes are made of brazed steel pieces joined together with brazed rods. They are compositions in many planes. Harry used this technique on very large screen dividers. Harry made these from 1954 until the end of the 1960's. His first commission for GM was a multiplane. During the 1960's harry made extremely colorful panels. The planes were enameled. These works are more geometric and, as opposed to the rectangles of the earlier screens, use the triangle as their main component.

Spillcast were made in the late 1950's and the 60's where Harry and his helper(s) pored bronze directly
on the ground, in sand, etc. He then, swiftly created changes in the hot metal by moving it with a rod, tool
or threw and placed stones in it etc. They are like magma and have incredible colors resulting from the natural oxydation ot the cooling of the metal or from Harry adding salts and chemicals or spraying with water while hot. The largest one was made for the Dulles airport in the Washington DC area. Nine panels that were molten in a single day. The entire work measures 8feet by 36 feet. It is currently in storage and has not been seen sincea renovation of the original installation location in the 1970's.

Sprays are very gracious bunches of stainless steel wires that sway when touched or are moved by air currents. They are not sonic,but resemble more closely an underwater algae. They always have a twist where they are connected to their base. Their sizes vary from 12 inchesto around 50 inches. My favorite is in the Hirshorn Museum. Another artist named Len Lye used the same shape and added motorized motion.
The delicate-looking straw pieces remind you of a game of pick up sticks, randomly put together and glued. The reality is, there was nothing left to chance, Harry worked these compositions very carefully. Again, they are made of brazed steel wire, and look like they are very light and airy. The largest of these was commissioned by Minoru Yamasaki for the Northwest National Life Insurance building lobby,located in downtown Minneapolis, today occupied by ING direct. The sculpture spans 14 feet high by 46 feet wide by 4 feet deep.
Tonals or sounding sculptures or Sonambient (r) are the type of sculpture that Harry is best known for. He had a real love for those as they have sounds that resemble bells. They do not take a lot of floor space and the combination of rods is infinite. The sizes vary from ten inches to nineteen feet in height. Some are in clusters, some in line, some have pods that tops the rods. These can be thick or thin round cylinders. Harry had over a hundred of them in his barn where He created music and gave concerts. May be a fit description would be "metallic harps" . The sounds are very beautiful. Many musicians have incorporated the tonal sounds in their compositions.Harry made them from 1960 all the way to his death in 1978. The largest array is in Chicago, designedfor the reflecting pool in front of the Standard Oil Building and installed in 1975.
Trees are made from brazed steel and were works made in the 1950's. The most famous of them was exhibited in the US pavilion at the Brussells World's Fair in 1957 It measures 7.5 feet by app. 6feet by 4 feet. Some are gilded. they were made only for a short period of time. None were made after the 1960's.This shape evolve in the bush shape. We've found that some of the bushes are mounted on tall stems and look like the tree form.
Willows are made primarilly of stainless steel. There are a few exceptions. Like sprays, the thin rods are allowed to droop gently from a center pole, which determines the overall height of the sculpture. The extended length of the wires gives the graceful waterfall effect They measure from 32 inches to as high as 96+ inches. Willows are interesting when readied for storage. As all the rods extend in line from the base, they can be transported like a very long tube with a base.Harry used the same shape to create a series of ceiling-mounted sculptures in Seattle's first national bank(Seafirst).
Wire Construction differ from straw category inasmuch as they are usually in a frame ( there are exceptions) and usually can incorporate different metal planes or constructions or other shapes. the wires that hold the planes are very thin and the frame can be one inch thich. Sometimes the framework resemble a box or circles made out of wires and the elements look like they are floating in it. We've also found some that are built on a wire base varying in shape. The early ones can be kinetic, a little like Calder's stabiles. Most are made of very thin brazed wires. Some incorporate color pieces.
