This summer, now through September 6, the EcoTarium (222 Harrington Way in Worcester) is hosting a traveling exhibit:  Wild Music — Experience the Sounds and Songs of Life.  Learn about and experience the music of humans and other living creatures.  Open during normal museum hours, included in museum admission.  Soundtastic Saturdays (weekly all summer at 2:30PM) will offer science discovery programs to explore how humans and other animals perceive and produce sounds.
