In January 1913, Respighi left Bologna to become professor of composition at the Liceo Musicale di Santa Cecilia in Rome, a position that he held for almost a decade. Composers Vittorio Rieti and Daniele Amfitheatrof were among his students during this time. The busy atmosphere of Rome unnerved Respighi, however, and composing and teaching became increasingly difficult. He became withdrawn, suffered from irregular sleep, and wished to return to Bologna. Later in 1913, Respighi went back to Germany for some performances and then upon returning to Rome, turned his attention primarily on composition.
