Moo (eg. Mō) comes from Japanese and means already/soon/again. The piece is initially a duet for two celli and the main idea is two parts that try to get as close together as it goes within the usual chromatic tone system. They never play the same tone except at the end when they both land on a quarter note raised A, midway between A and A#. However, it is an octave apart – the same tone but still not.
