Composers

Composers are individuals who create original music by shaping melodies, harmonies, rhythms, and forms into notated scores or other performable instructions. They write for a wide range of settings, from solo instruments and chamber groups to orchestras, choirs, operas, and ensembles used in film, television, and video games. Some compose for traditional concert repertoires, while others tailor music to commercial media or community contexts. In many traditions, the composer also makes decisions about instrumentation, texture, tempo, dynamics, and articulation, and must consider how performers will interpret the work.

The composing process varies by tradition but commonly includes idea generation, thematic development, orchestration, notational detailing, and revision. Collaboration with performers, conductors, librettists, producers, and editors is common, especially in opera, film scoring, and contemporary music theater. Notation and publishing help preserve works and enable broader performance; copyright and royalties support a composer’s livelihood.

Historically, the role of the composer has evolved. In medieval and Renaissance Europe, many works circulated through manuscripts with anonymous or collective authorship. From the Baroque through the Romantic periods, individual composers became celebrated creators whose names identified distinct styles and schools. In the 20th and 21st centuries, composers have experimented with new tonal systems, electronic technologies, and cross-genre collaboration, expanding what counts as music and who can be a composer.

Contemporary composers work in academia, industry, or as independent artists, and many genres—classical, film, pop, world, and experimental—include practitioners who write music rather than solely arranging or performing it.
