Hudson, N.Y. — On a warm day in late September, mezzo-soprano Hai-Ting Chinn sat for an interview at an open-air cafe on 44th Street in midtown Manhattan. Dressed conservatively and sporting a prim, black choker, she looked pretty much like any other young, Yale-educated, musically gifted science geek of mixed Chinese and Jewish ancestry. So you’d have no way of guessing that one of her greatest not-so-secret pleasures is donning a wearable model of the solar system and vocalizing rhapsodically about stuff like compression waves and subatomic particles. Chinn sees genuine beauty in these things and wants all of us to enjoy the aesthetic pleasures of contemplating science’s most elegant axioms. For this reason, she put together a fully staged “opera with experiments” that celebrates the beauty inherent in all things scientific. The product of a multi-year residency at HERE Arts Center in New York City, “Science Fair” is nothing less than a smorgasbord of scientific delicacies. This “love-song to science” is 70 minutes long, and you can hear the whole enchilada when she takes the stage with pianist Erika Switzer at Hudson Opera House Saturday, Oct. 26, at 7 p.m.
