Now there are lots of songs that after a few notes you can recognise it.
Lots of books and movies and TV shows can be recognised from a quote.
But my favourite bit of shorthand doesn’t require real music or words.
Hold up your right fist by your head. Make a few stabbing gestures while going “RE RE RE”. Ask people what it is and they’ll all say “Shower scene” or “Psycho” or “Hitchcock” or once in a while “High Anxiety” (if they do point out that Barry Levinson played Dennis).
Everyone picks it. Know any others without words or music?
