A small string section’s worth of violin stars will celebrate the centenary of the violinist Isaac Stern. Andris Nelsons will conduct the Boston Symphony Orchestra in the third act of Wagner’s “Tannhäuser.” And Paul Lewis will play the five Beethoven piano concertos.

Those are among the highlights of the 2020 season at Tanglewood, the Boston Symphony’s summer festival in the Berkshires, which was announced on Thursday.

The soprano Angel Blue, who opened the Metropolitan Opera’s season as Bess in “Porgy and Bess,” will also open the Boston Symphony’s Tanglewood season on July 3, singing Barber’s “Knoxville: Summer of 1915,” conducted by Ken-David Masur.

The 100th anniversary of the birth of Stern, the violin virtuoso who led the effort to save Carnegie Hall, will be lauded with a series of concerts the weekend of July 24. The violinist Midori will play Bernstein’s “Serenade (after Plato’s ‘Symposium’),” which Stern premiered with its composer conducting the Israel Philharmonic in 1954. The violinist Augustin Hadelich will play Dutilleux’s “L’Arbre des Songes,” which was written for Stern.
