The tsungi horn is a fictional instrument from Avatar: The Last Airbender, the animated series that first aired in 2005. It is most closely linked to Uncle Iroh, the retired general known for tea, patience and music aboard ship. Fans later lifted horn clips and recreations onto soundboards and short video edits, where the name stuck as shorthand for Iroh's calm presence. It remains used because Avatar fans instantly recognise the reference, while other viewers still hear a funny, mellow horn cue.
