Object
Doctor’s Yeti-Control Descant Recorder
A descant recorder used by the Doctor to emit musical tones that temporarily control and direct hostile Yeti guards. A reusable tool appearing across multiple episodes (The Abominable Snowmen, The Web of Fear), it enables safe passage and infiltration by maintaining Yeti obedience. Unlike the summoning microphone, it does not call Yeti but suppresses their aggression.

Purpose
To produce melodic distraction through controlled breath across its air channel and finger placement on the holes
Significance
Serves as an impromptu sonic disruption that momentarily diverts the Doctor’s focus, inadvertently revealing the Medusa-like danger of the Mandragora Helix on the viewscreen. Its innocent musical act becomes the catalyst for the TARDIS’s violent temporal displacement into the Helix’s vortex.
