The trumpet was found on the middle gun deck of the wreck. It is a sophisticated orchestral trumpet made in Nüremberg 1654 by the recognised trumpet maker Michael Nagel. Musical archaeologists were surprised by the find, since such a sophisticated instrument was not likely to be found onboard a warship. One would expect simpler trumpets for ceremonial purposes under these extreme conditions at sea.
The Nagel trumpet was not the only musical instrument found onboard. The remains of three violins, one viola da gamba (a cello-like instrument) and another trumpet (examples of the musical world of Kronan) have also been excavated. These finds show another aspect of Kronan, apart from the war-machine they provide a glimpse into the daily lives of crew and officers.
