The Official Classical Singles Chart will reflect the most popular individual tracks bought by classical music fans each week.
The past two years have seen a surge in individual track download sales - up 46% in 2011 compared to 2010 (1.22m vs 834,000), according to the OCC.
While these numbers were boosted by the success of the Military Wives' Christmas Number 1 Wherever You Are (which was downloaded 191,000 times on its own in 2011), download sales would still have been above 1m for the year, for the first time ever.
This surge is continuing in 2012 - in the first quarter of this year, some 284,000 classical downloads were sold, a 34% increase on the 212,000 sold in Q1 2011.
The Classical BRITs has also confirmed that it will launch a Top Single Award at this September's 2012 Royal Albert Hall show. It will be publically voted for with the shortlist based on the OCC's poll of the biggest selling downloads over the previous 12 months.
The new Official Classical Singles Chart will be announced every Monday at www.OfficialCharts.com and will be based on sales from the UK's leading download stores, ranging from iTunes, Amazon.com and 7Digital.com through to Tesco.com, HMV.com and Sainsbury's.com, among others.
The first chart will be unveiled at 1pm this coming Monday 28 May 2012 at www.OfficialCharts.com.
