The total needed, though, is more than the orchestra has ever before attempted to raise: an estimated $160 million to $170 million for operations and endowment.
All of this will be sought as the orchestra does its usual stumping for the annual fund.
"We still have an awful lot of money to raise," said Worley, who has, with his wife, given $5 million to the recovery effort. "It's been a long struggle, it's not over, but we're still standing and we're still playing, and Philadelphia is increasingly responding to us, and I couldn't be more encouraged."
Even before the orchestra filed for Chapter 11 bankruptcy on April 16, Worley said the city was "in grave danger of losing this orchestra."
Asked whether that danger still exists, he said:
"We have a lot of work to do to keep it. We are dedicated to keeping the Philadelphia Orchestra, not just some group of musicians, on our stage."
The musicians themselves are in the process of determining that outcome. Several prominent titled players - clarinetist Ricardo Morales, trumpeter David Bilger, and cellist Efe Baltacigil - already have accepted positions elsewhere, and another wave of departures is on the way.
Principal trombonist Nitzan Haroz has won an audition with the Los Angeles Philharmonic. He declined to comment because, he wrote in an e-mail, "the details regarding the LA position are still being worked out."
Jonathan Chu, a section violist who joined the orchestra in 2009, has accepted the same position with the Boston Symphony Orchestra.
Others are said to be taking auditions or considering teaching positions.
Not every player is citing deep concessions in the new labor contract as a reason for leaving, but some are.
