Place this theme at the very start of the edit as the title sequence, then follow it with cartoon chase music once the action kicks in, and save any reaction sounds for after the first gag lands.

This is the 27-second orchestral opening theme for Tom and Jerry, a bright MGM cartoon fanfare built on strings and brass with a jaunty, bouncing rhythm. It feels cheerful and mischievous, sparking instant nostalgia for classic cat-and-mouse chases. The music comes from the American animated series created by William Hanna and Joseph Barbera for Metro-Goldwyn-Mayer, first released in 1940.
