Bill Close is the designer and founder of MASS Ensemble and MASS
Productions. His work started with small sound sculptures in art school
and has grown into large-scale, musical performance installations.
Close studied sculpture, sound design and performance at the Art
Institute of Chicago. There he developed original sonic sculptures that
evolved into functioning, fully tunable musical instruments. Using the
long-string technology he developed, Close designed and created musical
installations transforming architectural space into giant stringed
In the fall of 1999, Bill invented and created the first Earth Harp. In
addition to the Earth Harp, he has created hundreds of instruments
ranging in size and scope from 3 inches to 1100 feet.
Many world-recognized organizations have awarded Close installation and
Bill also teaches and lectures about his instruments and installations
as well as instrument building and design at universities, schools,
museums and performing arts centers including Talieson (Frank Lloyd
Wright’s School of Architecture), Milwaukee Museum of Art, and the Art
Institute of Chicago.
“It is through the resonance of design that I find a true understanding
of music and its powerful relationship to life.” - Bill Close
