Desplat said that "This instrument comes back quite often playing the same melody. The notes from the first theme were played on clarinet, by virtuoso Dan Higgins. There is a great electric energy coming from the musicians." ĭesplat approached a light-hearted tone for the film, which was felt right, according to Renaud. Desplat said, "At times the score is really full blast with a hundred and more musicians. Desplat brought in an 85-piece orchestral and a 35-member vocal choir, for scoring the film. Initially, Desplat intended to use jazz music, but with the limitation of using only jazz, and wanting to explore several territories, such as melodies and adventurous themes, he decided to added an orchestral music. Swing, classical references, jazz, a symphony chorus, humor, tenderness…all these things were there, offered to me." For taking place in New York, there was something that felt very right." Despite being a jazz-music lover, he did not find the right project for using jazz music, which he admitted: "I haven’t really had an opportunity to really use it in a big scope for cinema, and this was a great option for me to do that. In an interview to Entertainment Weekly, Desplat said that " Chris Renaud showed me some excerpts of the film and they were so funny and beautifully shot that I was already excited, and then we had a chat about music and very quickly we realized that we could go to a territory which I’ve not really explored in movies in America, which is jazz meeting orchestra.

In December 2015, Desplat was hired to score music for The Secret Life of Pets. Every single entry, every single move and motion of the characters, must go with music."

“There’s also a lot of music, surely, and maybe sometimes much more than a drama or a comedy.

"An animation movie requires work on the sound and music which is more important than a live-action movie because it’s non-existing persons…you have to create life! And music, in that sense, is very important,” he explains.
