Why is Beethoven’s Ninth Symphony difficult for choirs to perform?

Ludwig van Beethoven’s Symphony No. 9 is considered notoriously difficult for choirs to perform primarily because of the composer's approach to vocal writing. Beethoven often treated the singers as if they were instruments rather than voices, placing significant technical demands on the performers.1

This approach was highly unorthodox for the time, as the symphony was a genre traditionally reserved for instrumental music. By integrating a full chorus and vocal soloists into the final movement to set Friedrich Schiller’s poem "Ode to Joy," Beethoven created a hybrid work that challenged contemporary expectations and pushed the capabilities of the vocalists involved.23
