The database includes the classical programs from 21 of the largest American symphony orchestras. Each orchestra can be viewed on its own tab or by selecting that filter. Filters can also be used to highlight a specific piece, composer or works written by living composers or specific nationalities.

Repertoire from galas, touring, chamber series, pops or family concerts are not included in the main mastersheet or individual orchestra tabs, but those concerts are viewable in separate tabs included in the database. For more information on the methodology, see below. To see some of the initial findings visualized, click here. To see a list of the most performed concert repertoire, click here.

Update: The Nashville Symphony Orchestra has been added to the database bringing the total orchestra number to 22. Numbers from that addition are not included in the initial findings.

More from Orchestra Season by the Numbers series:


  • The orchestras included are the Atlanta Symphony Orchestra, Baltimore Symphony Orchestra, Boston Symphony Orchestra, Chicago Symphony Orchestra, Cincinnati Symphony Orchestra, Cleveland Orchestra, Dallas Symphony Orchestra, Detroit Symphony Orchestra, Houston Symphony, Los Angeles Philharmonic, Milwaukee Symphony Orchestra, Minnesota Orchestra, Nashville Symphony Orchestra*, National Symphony Orchestra, New York Philharmonic, Philadelphia Orchestra, Pittsburgh Symphony Orchestra, San Diego Symphony, San Francisco Symphony, Seattle Symphony Orchestra, St. Louis Symphony and Utah Symphony – Utah Opera.
  • The programs and repertoire included are from the 2014-2015 season as listed on each orchestra website and literature prior to the start of the season.
  • Calculations for the initial findings and infographic are weighed by the number of times a piece of music will be performed in concert.
  • Gala concerts, touring, chambers series, pops and family concerts are included but are in a separate category from the main classical programs. The infographic and initial findings calculations excludes these concerts.
  • While technically touring, the Cleveland Orchestra’s concerts in Miami are included in the main classical programs as its performances in Miami are an annual part of its season.
  • To be included in any of the categories, concerts must use musicians from the listed orchestra.
  • Additionally, pops and family concerts listings are not extensive, as full program repertoire is often not included online for these concerts.
  • Composer nationalities are based on information from the New Grove Encyclopedia of Music and Musicians as accessed through Oxford Music Online. When no entry exists for a living composer, nationality information comes from the best available biographical information usually from the composer’s website.
  • Composition date is based on the best available scholarship of the year in which a piece was completed.
  • Later revisions are not included in the composition date unless a concert program specifically denotes a different version of the original piece. For example, Stravinsky’s Firebird Suite was completed in 1910, but the Pittsburgh Symphony Orchestra will perform the 1919 version and the St. Louis Symphony will perform the 1945 version for ballet and orchestra, which is included in the composition date for those entries.
  • In most cases, composition date information comes from the International Music Score Library Project / Petrucci Music Library.
