This is a video of musician Michael Tan performing one of Bach’s crab canons with a replicant of himself. A crab canon is “an arrangement of two musical lines that are complementary and backward,” similar to a palindrome. Wo, Nemo toss a lasso to me now! The video features Michael playing the canon both forwards and backwards at the same time thanks to the marvel of modern video editing. Or, and just hear me out here– “It’s not his twin.” How do you know? Maybe I went to school with the Tan twins.
