Employment and Auditions


Chicago a cappella will be holding auditions for all voice parts in January/February 2023


The audition will consist of singing two contrasting selections.  One of your prepared selections should be a classical aria or art song, and the other a decidedly non-classical selection. Together these should showcase your technical prowess and stylistic versatility. Off-book performance is preferred though not required.  An accompanist will be provided; please bring sheet music for the accompanist.  Due to time constraints, we may not hear the entirety of both prepared pieces.  You may also be asked to vocalize for range purposes and/or perform a short ear-training exercise.

To request an audition, e-mail a note of interest and resume, indicating your voice part, your preferred audition day, relevant experience, and highlights of ensemble and solo experience, to Kat Best at  Requests from qualified applicants will be accommodated on a first-come, first-served basis.

Auditions take place:

  • Monday, Jan. 23, 2023, 4:30-6:30pm in Oak Park
  • Tuesday, Jan. 31, 2023, 4:30-6:30pm in Oak Park
  • Tuesday, Feb. 7, 2023, 4:30-6:30pm in Oak Park

Successful auditionees may be asked to attend callbacks in spring 2023.



The following musical skills are required from ensemble members:

Strong solo technique; technical ability to sing both fully-voiced (with healthy vibrato) and with no vibrato; strong sight-reading skills; minimum of 2 years singing at a professional level, with experience in traditional and contemporary music, as well as a strong ear for new styles that may be unfamiliar; expertise at holding a vocal line individually within a group; strong stage presence; ability to respond quickly to instruction in rehearsal; superb language skills (knowledge of IPA strongly preferred).



Chicago a cappella spans a repertoire from Gregorian chant to the Beatles and beyond. Under the leadership of Artistic Director John William Trotter, the group presents concerts with musical preparation by Trotter and guest music directors. Known for creative programming and a personal connection to audiences, Chicago a cappella performs an annual series with concerts in Chicago, Evanston, Oak Park, and Naperville, with occasional guest appearances in town or on tour.  Current pay rates are $210 per performance for series concerts and $33.60/hour for rehearsals.  Typically, our series concert programs each involve 8 rehearsals and 4-6 performances.
