"Rondo: an instrumental composition typically with a refrain recurring four times in the tonic and with three couplets in
contrasting keys." --G. & C. Merriam Co. New York 1973
The composition will be played on three instruments, a cryogenic space surveillance sensor, a document scanner and an
optical image correlator. The performer will take the liberty of including an introduction and a coda. After the first
couplet the listeners may sing along with the performer.
