True to its title, this original work is a study in echo between a 3-5 octave choir and a 3 octave choir. Easy-to-play full chords start the work off but progress to some chromatic changes. Things soon smooth out into a homophonic passage that leads to a section to be played with mallets on suspended bells. In lieu of a handbell choir to echo with, an optional organ score is included. Measures total 42.
