But the symphony said the plan released Thursday is not feasible. Musicians hailed the ideas as “a path to a fair resolution.”

U.S. Sen. Carl Levin and Gov. Jennifer Granholm said in a letter that the symphony and its musicians are “within striking distance of an agreement” to end the walkout that began Oct. 4.

The politicians said both sides should agree to a 3-year contract with total compensation of $36 million. They say that’s down from the previous contract’s $48 million but more than the $33 million to $34 million management proposed.

Board Chairman Stanley Frankel said the $36 million is “beyond what every consultant and our board have said is feasible.”
