This piece breaks down an octave into intervals in a colorful fashion. The rhythm of the colored patterns lends motion and different interpretations to the piece while allowing the background colors to migrate through the piece, as companion tones in music do. An interval is simply described as “the difference in pitch between two musical sounds” but originates from the Latin “intervallum” which means the space between ramparts. This piece also spans the spatial chasm in the hallway with a portion installed along the glass wall above.
