Vulcan marriage drum

The Vulcan marriage drum was a musical instrument from the planet Vulcan.

When the male crew of the USS Enterprise (NCC-1701) was under the spell of the female inhabitants of the second planet of the Taurean system, the ship received a signal from the planet. To Spock, it was identified as the sound of a Vulcan marriage drum, followed by an audio-visual suggestion of the female who was playing it.
