What Metropolitan Orchestra of Saint Louis does
Mission
The mission of MOSL is to provide a high quality orchestral ensemble for St. Louis area musicians, where professionals can hone their skills while mentoring student intrumentalists, vocational players and music teachers, and sharing the joys of playing great music. MOSL is composed of working St. Louis area professional musicians, music teachers, and student musicians, who are seeking a venue to perform standard symphonic repertoire at a very high level. The diverse personnel of the orchestra allows seasoned professional musicians to continue sharpening their skills, while providing unique educational experiences for younger student musicians. Together, the unified ensemble fosters a cooperative learning environment in an artistic atmosphere that brings the joys of music making to the community through accessible and affordable public concepts.

69% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund METROPOLITAN ORCHESTRA OF SAINT LOUIS.
Largest funder’s share by year: 2017 45% · 2018 97% · 2019 71% · 2020 66% · 2021 98% · 2022 99% · 2023 79% — growing more concentrated.

In-state vs out-of-state, by year

Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
