The 1895 Theodor Jacobsen Observatory comes to life through an awakening of the work of German/English astronomer and composer William Herschel (1738 –1822). Inside the observatory dome, violinist Tekla Cunningham will perform a variation on Herschel’s Circle of Fifths and on the bottom floor, a timpani drum will emanate low frequencies to commune with the forces of the cosmos. ...For this occasion, astronomer Woody Sullivan and music historian Sarah Waltz evoke Herschel’s adaptations of his astronomical knowledge to music. Furthermore, in the sky this evening one can find the constellation Sagittarius, traditionally pictured as a half-man/half-horse creature (centaur) with a drawn bow.
