Abstract: An acoustic sculpture 10 having a main frame structure 12 including an upper support member 14 and a lower support member 16, and a plurality of tube assemblies 24 of varied mass. A tube assembly 24 includes a vertical chime tube 20 acoustically suspended from a coaxial mounting rod 28 mounted to a tube frame. The tube frame can include transverse straps (30, 32) mounted to vertical stiles (34, 34?) which are attached to the upper and lower members (14, 16). A striker assembly (48, 48?) is attached to the tube frame, for example, the stile portion (34,34?; 34?,34??), and includes a housing (60, 60?) and an actuator button (50, 50?), accessible through a first aperture (64, 64?), operatively connected to transmit motion to a hammer head (54, 54?) to strike a chime tube (20, 20?) through a second aperture (65, 65?) in the back plate (63, 63?).
