My dance card for September seems to be rapidly filling up. On September 25 and 26, the Chamber Orchestra of Philadelphia opens its 2026-2027 season with Mozart 40, a triple bill of music spanning the half century or so between the late Baroque and middle Classical periods, a span quite appealing to my own musical affections. David Hayes will lead the orchestra in Mozart’s 1788 Symphony No. 40 in G minor, which Charles Rosen called “a work of passion, violence, and grief” in The Classical Style; Hayes will follow this with Johann Christian Bach’s 1760-or-so Symphony in G minor, Op. 6 No. 6, “arguably the darkest and most dramatic he composed,” said Tom Service in the Guardian in 2014; and the program will close with Schubert’s Symphony No. 5 in B-flat major, D. 485 of 1816, a conscious tribute to Mozart. “O Mozart! Immortal Mozart! what countless impressions of a brighter, better life hast thou stamped upon our souls!” went the slightly (though understandably) over-the-top appreciation Schubert wrote in his diary that year. Tickets are available now at this link.

The rest of the Chamber Orchestra’s season looks similarly enticing, with a holiday presentation of three Brandenburg Concertos and an all-Haydn evening of his early symphonies on the schedule. More about the season here. A series of intriguing discussions about Bach and Beethoven accompanies this year’s concerts.
