The Oklahoma Summer Arts Institute Orchestra is a full symphony orchestra. All participants rehearse with professional orchestral musicians under the direction of internationally recognized conductors. The daily schedule includes full orchestra rehearsals as well as individual and sectional coaching. Repertoire consists of standard and contemporary symphonic literature. Students may also participate in chamber music and ensemble work. The orchestra performs two concerts during the Institute, and the chamber music ensembles will have one evening performance.

Students may NOT audition on the following instruments: English horn, piccolo, saxophone, contrabassoon, bass clarinet, E-flat clarinet, bass trombone, or euphonium (baritone).

Requirements for Applicants

1. Complete an online application and schedule your audition no later than noon the weekday before your desired audition date. See dates in right side bar or view full audition schedule here. Audition spaces fill quickly, so schedule as soon as possible.

2. Bring a government-issued I.D. or birth certificate to your audition for age verification purposes.

Audition Guidelines

The audition consists of 4 components.

1. Scale

2. Solo Piece

  • All applicants must perform a work, maximum of one minute, which represents overall musicianship. The work does NOT have to be memorized, but should demonstrate your ability to play lyrically and technically. The work can be a solo, etude, All-State etude, or excerpt from an orchestral work. NO accompanists.
  • Applicants must provide a copy of the work performed for the audition.
