Vulcan marriage drum
From Memory Alpha, the free Star Trek reference
The Vulcan marriage drum is a musical instrument from the planet Vulcan.
When the male crew of the USS Enterprise was under the spell of the female inhabitants of Taurus II, 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. (TAS: "The Lorelei Signal")
