Film scoring is the job of writing original music to fit a finished or nearly finished picture. Berklee's career guide puts the composer's task in one line: use music to mirror and heighten what's happening on screen 1. Everything else in this guide is about how that actually happens, who's in the room, and what's shifting in 2026.

The short version

Berklee calls film and TV director-driven and producer-driven art forms, and the composer works to that vision 1. The composer and director decide where music goes. The composer writes it, usually as detailed computer mockups first. An orchestrator turns those sketches into a full score, copyists prepare each player's part, a contractor books the musicians, and a scoring mixer records and mixes the sessions. A music editor fits the music to the final cut and looks after it at the dub. Then, often, it becomes an album. Each step has its own specialist.

Who does what

The composer

The composer leads the music. Berklee describes the work as collaborative and driven by the director and producers rather than by the composer's own taste 1. A score can borrow from any style the film needs: the time and place, the mood the director wants, the story and its characters 1. The skill list is wide: writing and reading music, arranging and orchestration, theory, performance, conducting and an understanding of filmmaking itself 1. Most film composers work as independent contractors, from home studios, commercial facilities or a hybrid of both 1.

Who owns the music. Leading the music isn't the same as owning it. Under US copyright law, a commissioned contribution to a motion picture can be a work made for hire if both sides sign a written agreement saying so, and then the hiring party is treated as the author and the copyright owner 9. The Society of Composers & Lyricists calls work-for-hire contracts standard industry procedure, and notes that signing one doesn't mean giving up performance royalties: both ASCAP and BMI pay the writer's share to the composer, not the employer 10. That money depends on cue sheets, the log of every piece of music in a production. The production company files them, and BMI tells composers to check them, because they're how performing rights organizations track music in film and TV 11.

The composer's assistant

A composer's team can range from a single assistant to a larger setup 4. The assistant's work, as Berklee lists it, covers preparing sessions and templates, organizing project files, creating mockups and preparing materials for orchestrators, copyists, music editors and recording sessions 4. We cover how people get these jobs in How to Become a Film Composer in 2026.

The orchestrator

The orchestrator turns a composer's sketches, MIDI mockups or reduced scores into a detailed full score for the ensemble, choosing instrument combinations, voicings, articulations and registers within the schedule and budget 3. Berklee separates traditional orchestrators, who work in notation, from MIDI orchestrators, who work with sample libraries and synth programming 3. Orchestrators are expected at the recording sessions 3.

The copyist

Once the orchestrator is done, the copyist proofreads the score and produces a transposed part for every player 14. Berklee lists copyists among the orchestrator's closest collaborators 3.

The music contractor

Someone has to put players in the room. Berklee Online says music contractors find the session musicians and conductor for a score and act as the go-between for the musicians, the client and the union 13.

The scoring mixer

The scoring mixer records the orchestra on the scoring stage and shapes the composer's music for the final mix. CineMontage, the Motion Picture Editors Guild's magazine, describes the job as capturing the composer's music in the live atmosphere of the stage and acting as a link to the dub stage 12.

The music editor

The music editor is, in Berklee's phrase, part sound editor, part project manager and part musician 2. They sit in the spotting sessions, keep the composer updated as the picture changes, build temp music for test screenings, cut cues to fit scenes, and represent the composer's interests at the final dub 2.

The music supervisor

Songs are a separate job. Berklee describes the music supervisor as the person who works with the director or showrunner to choose songs and then clears the rights to use them 15.

The process, step by step

1. Temp music

Before the score exists, the film is often cut against borrowed music. Music editors make these temporary soundtracks for test screenings and pick temp music for emotional scenes 2. Temp tracks shape what directors expect, which is why they matter so much to the composer who has to replace them.

2. Spotting

At the spotting session, the composer and director decide how many cues the film needs, where each one starts and stops, and what each should do 2. The music editor is in that room 2. Our spotting session guide walks through who else is there, what the spotting notes look like and how to prepare.

3. Writing and mockups

The composer writes, usually producing mockups the director can hear before anything is recorded. Those mockups, sketches or reduced scores are what the orchestrator works from 3. The tools for this stage are covered in The Film Scoring Software Stack in 2026.

4. Orchestration, parts and recording

The orchestrator delivers the full score 3, copyists produce the parts 14, the contractor books the players 13, and the music is recorded. The range is wide. USC's screen scoring students record with ensembles of between 5 and 65 players at Los Angeles rooms including Capitol Studios and the Warner Bros. Eastwood Scoring Stage, under AFM Local 47 guidelines 5. At the top end, James Newton Howard's latest Hunger Games score was recorded at Abbey Road with 96 musicians and two choirs, per his Instagram as reported by EntertainmentNow 7.

5. Mixing, editing and the dub

The scoring mixer mixes the recorded score 12. The music editor fits it to the final cut and represents the composer at the final dub 2. The production company then files the cue sheets that drive the composer's performance royalties 11.

The timeline is not fixed

The textbook order puts the composer near the end, but not every film works that way. On Sirāt, Kangding Ray told Filmmaker Magazine that about 80 percent of the music was finished by the time shooting began 8. Berklee notes the profession runs in extreme cycles of activity with immovable delivery deadlines 1.

What's changing in 2026

  • Where sessions happen. California's new post-production credit, effective January 1, 2027, counts music editing and scoring as qualifying costs and gives scoring the top 50 percent rate 6.
  • Stems are standard. Separating a mix into stems is now built into DAWs; Ableton, for one, says the stem separation in Live Suite runs locally 16. That changes how composers work with temp tracks and reference cues.
  • AI guardrails. AFM Local 47 has asked that state money not fund productions that swap human art for AI-generated film scores 17.
