Bagpiper → It is formed from "bag" (from Old Norse *baggi*, meaning a sack or pouch) and "piper" (from Old English *pipere*, meaning a person who plays a pipe or flute). The word "bagpiper" refers to a person who plays a musical instrument consisting of a bag and pipes.
Think of a 'sack' ('bag') that holds air and 'a person who plays a pipe' ('piper') — that's why a bagpiper is someone who plays music using a bag and pipes.
