🎯 Role Definition

A Jazz Arranger designs, adapts, and organizes musical material for jazz ensembles and related projects. This role requires deep knowledge of jazz harmony, orchestration, voicings, and idiomatic writing for rhythm sections, horn sections, and vocalists. The Jazz Arranger produces accurate full scores and individual parts, delivers rehearsal-ready charts, collaborates with bandleaders, producers, and soloists, and provides mockups and notation files for live performance, studio recording, broadcast, and educational contexts.

The ideal candidate is fluent in notation software (Sibelius, Finale, Dorico), comfortable producing MIDI/audio mockups in DAWs (Logic Pro, Pro Tools), and experienced in transcription, reharmonization, and arranging across formats that include big band, small combo, vocal charts, and orchestral/jazz crossover.

Entry Point From:

  • Professional session musician or sideman with demonstrated arranging experience
  • Graduate or undergraduate degree in Music Composition, Jazz Studies, or Arranging

  • Music Educator specializing in jazz arranging and composition

Core Responsibilities

Primary Functions

  • Create fully notated jazz arrangements for ensembles of all sizes — from small combos to big bands and orchestral-jazz hybrids — ensuring idiomatic writing, balanced voicings and playable parts for each instrument.
  • Transcribe recorded solos, comping patterns, and ensemble voicings by ear, producing accurate lead sheets, transcriptions, and performance notes for rehearsals and recordings.
  • Reharmonize melodies and craft alternate chordal treatments (substitutions, modal interchange, polychords) to enhance musical interest while preserving the integrity of the original tune.
  • Produce clear, rehearsal-ready full scores and individual parts in industry-standard formats (PDF, MusicXML, Finale/Sibelius/Dorico files) including rehearsal letters, measure numbers, dynamics, articulations, and performance notes.
  • Arrange vocal charts with strong lead-line support, background vocal arrangements, and studio-appropriate harmonies tailored to the singer’s range and stylistic approach.
  • Write idiomatic horn voicings (sax, trumpet, trombone) and manage range, breathing, and doubling considerations so parts are comfortable and sonically effective.
  • Create rhythm section arrangements that map out groove, feel, comping styles, and interludes — specifying piano/guitar voicings, bass lines, drum patterns, and percussion cues.
  • Prepare professional mockups and demos using MIDI, sample libraries, and DAW production to communicate arrangement intentions to clients and producers.
  • Collaborate with bandleaders, producers, soloists, conductors and music directors to align artistic vision, rehearsal schedule, and recording logistics.
  • Adapt arrangements for live performance constraints and instrumentation changes (e.g., reducing a big band chart for a quartet) while preserving core musical content and impact.
  • Deliver alternate versions and edits: radio edits, extended solos, vamp sections, fade-outs, and versions with/without leadsheets, as required for broadcast or licensing.
  • Notate and apply stylistic articulations, swing feel, phrasing guides, and idiomatic shorthand to ensure accurate stylistic interpretation by musicians of varying skill levels.
  • Manage transposition and create transposed parts for B-flat, E-flat, bass clef and F instruments; verify octave transposition rules and clef accuracy in final parts.
  • Attend rehearsals and recording sessions to provide on-the-spot edits, corrections, and conductor cues; coach sections on phrasing, dynamics, and blend when required.
  • Coordinate with copyists, librarians and contractors to ensure timely printing, binding and distribution of parts for tours, festivals and recording sessions.
  • Ensure charts conform to union and session requirements (where applicable), including deliverables for contractor packages, session calls, and contractual timelines.
  • Research original source material, historical styles, and arranger-specific idioms to create authentic arrangements for period pieces, tributes, and educational programs.
  • Prepare click tracks, tempo maps and conductor scores for studio recordings and remote sessions to maintain consistent tempo and alignment across multi-track productions.
  • Implement feedback loops with clients — iterating arrangements based on artistic notes, rehearsal outcomes, and vocalist or instrumentalist preferences.
  • Maintain version control and an organized digital library of scores, parts and mockups, and deliver final archived masters in agreed formats.
  • Handle licensing, permissions and clearance communications (arrangement rights, lead sheet usage, sampled materials) with publishers and rights holders when necessary.
  • Estimate time and cost for arranging projects, create project timelines, and work within budgets for freelance or contracted arrangements.

Secondary Functions

  • Support artistic development by mentoring junior arrangers, interns and student composers in chart preparation, orchestration and workflow best practices.
  • Assist in programming setlists and creating medleys, transitions and segues for concerts, broadcasts, and special events.
  • Produce educational materials and arrangement notes for use in clinics, workshops and syllabi for music schools.
  • Provide basic audio editing of demo takes and assemble package-ready files for submissions to festivals, venues and grant committees.
  • Participate in festival planning, repertoire selection, commissioning of new works, and collaboration with guest artists and conductors.
