At heart, dancing is moving to rhythm, and that means it’s almost inseparable from music. There are exceptions and variations: experimental cases when dances are created without sound; the Merce Cunningham/John Cage partnership, in which movement and music were created deliberately in isolation from each other so one would not influence the other, but were performed together; contemporary pieces with more or less arbitrary music that might better be described as “specimens of sound” (which, of course, can make their own sort of music); dances in which extended periods of silence are part of the score. But on the whole dance and music are pretty much happy bedfellows, cohabiting almost by instinct.

So the relationship between Chamber Music Northwest, Portland’s premiere summer music festival, and BodyVox, one of the city’s leading contemporary dance troupes, seems like a natural, and it’s beginning to be a tradition. This year’s collaboration, which opened Thursday night at the BodyVox studio in Northwest Portland and continues through July 23, brings a third player into the mix, too: that musically savvy playwright, William Shakespeare. Titled Death and Delight, the program pairs a version of Romeo and Juliet set on Sergei Prokofiev’s R&J Suite with a new version of A Midsummer Night’s Dream danced to Felix Mendelssohn’s ravishing score.
