NASHVILLE (AP) - The Country Music Association is giving $10 million to the Country Music Hall of Fame and Museum's $75 million expansion campaign.

The donation is the largest the Hall of Fame has received and will be used in part to help construct the 800-seat CMA Theater.

The expansion will more than double the museum's footprint to 350,000 square feet when construction is complete in 2014. The hall of fame kicked off its campaign in July with nearly $57 million pledged to help expand exhibit, performance, archival and educational spaces.

The CMA previously contributed nearly $5 million to the museum, and underwrites the hall of fame's induction ceremony. The hall of fame was established by the CMA in 1961.
