The pace is the oscillation that results from the maintenance of a sound, the internal rhythm of its sound structure, which makes it live and change from its emission until its extinction. In this study, the painter Raymond HAINS attempts a visual transposition of this acoustic law by filming his works through fluted lenses directly attached to the camera creating optical vibration effects that animate the shapes and colors and produce a colorful rhythm.
