At a meeting in Geneva today, the treaty organization that shook the music industry with new trade regulations on rosewood took formal action to clarify and potentially ease some of the regulations.

Rosewood is a prized "tonewood" used for musical instruments from guitars to clarinets and oboes.

The treaty cracked down on the material's international movements late last year to combat worldwide depletion of rosewood trees, driven by China's burgeoning demand for rosewood furniture.

Chicago Symphony Orchestra cellist Dan Katz has two cellos. The better one — the one he prefers to play with the orchestra — is 200 years old and has rosewood tuning pegs. When the orchestra went on an 11-concert European tour in January, he purposefully left it home.

"I worry with that instrument about international travel now, because of those pegs," Katz said after rehearsing for a performance of Schubert's Ninth Symphony earlier this month.
