Spock receives an audio-video suggestion of a Vulcan marriage drum
The Vulcan marriage drum was a musical instrument from the planet Vulcan.
When the male crew of the USS Enterprise was under the spell of the female inhabitants of the second planet of the Taurean system in 2269, 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 Taurean female who was playing it. (TAS: "The Lorelei Signal")
