Interest earned on the CBSO’s endowment will help to showcase individual talents during an annual programme of 20 Centre Stage lunchtime chamber concerts held in the CBSO Centre.
The CBSO’s public funding has been reduced by 24 per cent in real terms since 2010.
Following a £100,000 endowment gift from philanthropist and CBSO board member John Osborn, his donation for The Osborn Chamber Music Programme will be matched pound for pound by Arts Council England.
Mr Osborn said: “The CBSO is a terrific institution.
“I have loved it ever since my first concert nearly 60 years ago and I believe having a world-class Orchestra based in the city helps Birmingham to punch above its weight.
“We have to support them if we want to keep them.
“I am delighted to be able to support this particular strand of the CBSO’s work and I hope this might also encourage others to become similarly involved in the long-term support of this outstanding Orchestra.”
Mr Osborn, a long-term supporter of the CBSO, has served on the organisation’s board since 2012 and on the CBSO Development Trust since 2013.
He has also contributed to the cost of violinist Gabriel Dyker’s position in the orchestra for a number of years.
In addition to raising £1 million per year through annual sponsorships and donations, the CBSO Development Trust is also seeking to raise an endowment to secure the orchestra’s longer-term future.
Gifts made to the endowment before July 2015 are being matched by Arts Council England up to a total of £1 million, of which £700,000 has been raised so far.
CBSO director of development Simon Fairclough said: “John Osborn’s generous gift is testament to the admiration and support which our musicians inspire.
“With pressures on the public purse becoming ever more acute the need for support from private donors and funders is set to grow year by year.”
