TEHRAN, Apr. 25 (Mehr News Agency) -- After nine months without a permanent conductor, the Tehran Symphony Orchestra will begin rehearsals with new conductor Nader Mashayekhi next week, the Persian service of CHN reported on Tuesday.

Mashayekhi, who was appointed by the Music Center of the Ministry of Culture and Islamic Guidance, will begin the rehearsals on Saturday and is scheduled to conduct the orchestra for the first time in a concert at Vahdat Hall in late May.

The Policy-Making Council of the Culture Ministry will officially announce Mashayekhi's appointment as the permanent conductor tomorrow.

"We will elaborate on the orchestra's artistic seasons, the first of which will begin in autumn and continue until next spring. During each season, the orchestra will give several performances, each season focusing on one composer," said Mashayekhi, adding that the orchestra also plans to give performances of works by Iranian composers in Iran and abroad.

After the death of former conductor Fereydun Naseri, Ali Rahbari was appointed conductor, but he left the orchestra due to some problems.
