"Tom and Jerry" - a god work with only 185 episodes and 74 years to produce.
In Episode 81 of Cat and Mouse, "Cat's Concerto", Tom plays the piano on stage, Jerry the Little Mouse makes a mess on the piano, and all the keystrokes and background music match perfectly!
At the same time, the details of the score are also very good, and this episode of Tom's "Hungarian Rhapsody No. 2" makes tom and jerry a world classic.
At that time, computer technology was not yet developed, basically by hand, and I don't know how long it took to check to make this episode, and the production cycle is terrible

Meticulous to terrible sheet music details
Original score

Tom and Jerry 1940-2014 style comparison
(What happened to tom in '90-'94)
63-67 years of tom painting style mutation, weird background music, distorted scenes, dark tones, exaggerated expressions reflect a bit of childhood shadow feeling, but I still love ahhaha, making an avatar is very compelling
Finally, IMHO. The new version of Tom and Jerry is simply spicy chicken.
