Call for Scores!

The Concerto Chamber Orchestra, based in Los Angeles, at the University of Southern California, is composed of both non-music majors and music majors who work to foster collaborative music-making and to contribute to the culture of the surrounding community.

Due to COVID-19, CCO has adjusted its Call for Scores Guidelines for the coming season. Composers may submit as many works as they choose, in as many categories as they choose, so long as they pay a separate entry fee for each piece submitted. Selected works will be performed in the 2020-2021 season. All composers, regardless of age, nationality, etc. are eligible to submit.

DEADLINE: 8/21/2020 11:59 PM PDT [Pacific Daylight Time]

Three categories for submission

I. In-Person Chamber Ensembles (10 players or fewer)

II. Remote Recordings (full orchestra or smaller, click track required)

III. Asynchronous Works (full orchestra or smaller, works that are performable over Zoom, where exact synchronous playing is impossible due to variable delays in musicians’ internet connections)


Any subset of the following may be used (the full ensemble may only be used for categories II and III):

Winds: 4 flutes, 2 oboes, 4 clarinets, 2 bassoons (with doublings available for piccolo, english horn, and bass clarinet)

Brass: 4 horns, 3 trumpets, 3 trombone, 1 tuba

Percussion: timpani [up to 4], xylophone, cymbals, triangle, snare drum, bass drum, tambourine, maracas, gongs, chimes, celesta, and piano for up to 5 percussionists (including piano)

Harp, Strings (divisi permissible)

*Works may be written for indeterminate instrumentation or set instrumentation.

**While solo works will be considered, pieces for two or more players will be given preference.

***If your piece calls for additional instrumentation, we will do our best to accommodate it if your piece is selected. However, we are likely to prioritize works that fit within our standard instrumentation.

Difficulty Level

Many of our players are non-music majors who studied their instruments privately through the end of high school, so please take that into consideration. There will be at least one advanced player for each instrument who will be capable of playing any solos. Repertoire from previous concerts includes Holst’s Planets, Mussorgsky’s Night on Bald Mountain and Pictures at an Exhibition, Riley’s In C.


There is no strict duration limitation of the work, but in the past, most of the works we have chosen have been under 20 minutes with the majority being 3-12 minutes.


Please email scores and parts in pdf format to 11×17 in. for scores (may submit 8.5×11 in. for a chamber orchestra score) and 8.5×11 in. for parts.

[Note: In standard international sizes, this is A3 and A4 respectively.]

Please also include a recording or mockup when possible (highly recommended). If you are submitting to the “Remote Recording” category, a click track is also required in your submission.
