The film is directed by Brad Bird and featured musical score composed by Michael Giacchino, who also worked on the predecessor.

"[5] The scoring process delayed due to Giacchino's commitments with Spider-Man: Homecoming, War of the Planet of the Apes and Coco.

[11] The final recording sessions happened in May 2018, consisting of a 99-piece orchestra, conducted by Gordon Goodwin, and a brass-heavy band dominating the string section.

In an interview for Variety, Giacchino said that writing lyrics for the jingles "as a crazy idea "It’s as if, in that world, each of these characters had a TV show based on them and they know their own theme songs".

Jonathan Broxton wrote "If you like big band jazz and large, swinging orchestras in the [John] Barry/[Henry] Mancini tradition, then a great deal of The Incredibles 2 will be very entertaining.

"[12] Anton Smit of Soundtrack World wrote "The score itself is not very innovative since it is a continuation of the music from the first movie, but with that said, it also introduces some new melodies using the same vibe of the predecessor, like the new Elastigirl theme.

"[14] Filmtracks.com wrote "Incredibles 2 is a wholly functional score, but it doesn't play as memorably in the film despite its often stomping personality defined by far too obvious instrumental accents.

The trumpet wailing and repeated ensemble hits in super-melodramatic caper fashion are simply too saturated throughout this score for it to serve as a parody that succeeds without begging for too much attention.

The movie's Screenslaver hypnotism scenes forced Disney to release warnings about possible epileptic seizures amongst those in the audience so inclined, and Giacchino's score could have the same effect on your ears.
