An elisiar.

An Elisiar is an Edoan musical instrument. It is comprised of a triple horseshoe-shaped keyboard which operates an echo chamber, plus resonating bars traditionally made of bone and a Mobius strip-shaped xylophone. USS Enterprise Lieutenant Connors played the Elisiar. (TOS comic: "The Crier in Emptiness")

A'l'e'r'w'w'o'k of the A.C. Walden Medicine Show also played the Elisiar, though he was unable to use it during the group's tour of Troyius in 2381. (ST novel: A Singular Destiny)
