Fan Casting iSophagus in Sort by Tropes

The iSophagus is any instance where, by swallowing a musical device or instrument, the swallower no longer speaks but emits music. Sometimes, the person who swallows said item can magically control what is coming out of their mouth. Barring that solution, the person must inflict bodily harm to themself to "change the channel." Oddly enough, all that is required to make no noise is to shut their mouth. It stays in the person until it is expelled by either a cough, hiccup, belch, sneeze, or pretty much anything except going out the back door. Otherwise it's simply forgotten about.
