Marion Borgelt's commission for AMPC Capital at Angel Place is has been launched on November 3rd, 2020. Musical Spheres is a site-specific installation that subtly refers to the historical importance of music in Angel Place. For example, the WH Pailing & Co building and business in this precinct imported musical instruments such as pianos and published and distributed sheet music in the 1800s and today, the City Recital Hall still functions.
The kinetic artwork moves gradually in a circular motion, completing one revolution every two minutes, imitating the movement of "hammers hitting piano strings and the movement of musical notes on a score" (Borgelt). Borgelt notes that the actions of the forms complement the movement of people through the space; "referencing music through movement rather than sound".
