The music of Beethoven will be inescapable this year, as orchestras around the world celebrate his 250th birthday. But the Juilliard School has another anniversary in mind for its upcoming Focus Festival: the centennial of the 19th Amendment.

To commemorate the hard-fought moment when women could vote in the United States, the Focus Festival — “Trailblazers: Pioneering Women Composers of the 20th Century” — will present six free concerts, Jan. 24-31, in a globe-trotting program that features 32 composers from five continents. (The New York Philharmonic, Juilliard’s neighbor, is also celebrating the amendment with a commissioning initiative, Project 19, and a series of concerts beginning Feb. 5.)

Joel Sachs, Focus’s founder and longtime director, enlisted the Cuban-American composer and conductor Odaline de la Martinez to help assemble the program. Their work has been, to some degree, investigative: correcting mistakes in outdated or obscure published scores, and unearthing pieces that haven’t been heard for decades.

“A lot of these composers have disappeared because people don’t know what to look for,” Ms. de la Martinez said in an interview with Mr. Sachs. “And musicology used to teach only men. It’s about time to make cases for other composers, and women.”
