Pluto's Blue Note is a 1947 animated short film (6 1/2 minutes) from Disney, directed by Charles Nichols.
Pluto the Pup loves to sing but he's terrible at it. He tries to sing along with two twittering birds, a buzzing bee, and a chirping cricket, but they all cringe in horror at his tuneless howling. He trots over to the stereo store across the street, but his howls to the tune of the radio lead the store owner to turn the radio to news. A frustrated Pluto then sneaks into the store, hoping to listen to the radio, but then discovers something surprising.
- Aside Glance: Pluto winks at the camera when he realizes what he can do, then later turns to the camera and grins during the final Iris Out.
- Continuity Nod: Among the fangirls who swoon when Pluto sings are his two canine love interests, Fifi the Pekingese and Dinah the dachsund.
- Hollywood Tone-Deaf: All the animals as well as the store owner are offended by poor Pluto's howling.
- iSophagus: A variation. Pluto discovers that if he puts his tail on the record player it will function as a stylus and the music will come out of his mouth. A similar gag was used decades later in Disney feature Lilo & Stitch.
- Mime and Music-Only Cartoon: No dialogue.
- Protagonist-Centered Morality: Pluto steals a record player and uses it to trick the other animals into thinking he's a good singer.
- Tertiary Sexual Characteristics: The lady dogs that become Pluto's groupies have the standard long eyelashes that indicate "girl"; one also has a pink bow.
- That Syncing Feeling: The record starts to skip as Pluto is singing, but he recovers in time to maintain the charade.
