Ressikan flute

A Ressikan flute was a small woodwind musical instrument, native to the village of Ressik on the planet Kataan.

A Ressikan flute belonging to a man named Kamin was included aboard a probe encountered by the USS Enterprise (NCC-1701-D) in 2368, along with Kamin's life memories. Through the probe, Captain Jean-Luc Picard experienced the life of Kamin and of his endangered world, and during this experience, taught himself to play the flute. He retained this talent even after the probe ended its transfer. 

Picard thereafter considered the flute one of his most prized possessions, and continued to play it regularly. His playing was a key element of the bond between himself and Lieutenant Commander Nella Daren. 

As of 2379, the flute was kept on Picard's ready room desk.
