Cello Sonata no. 2 in F major, op. 123

The Cello Sonata No. 2 in F major, Op. 123, is a cello sonata by Camille Saint-Saëns. It was composed in 1905 during the composer's stay in Biskra, Algeria, and was written nearly 30 years after his first cello sonata. The sonata was dedicated to Jules Griset, a long-time friend of the composer, and was first performed privately by cellist Joseph Hollmann and Saint-Saëns himself before receiving its public premiere by Auguste Tolbecque and Aline Riffaud.

The work features contrasting themes, intricate interplay between the two instruments, and a range of expressive and technical demands. The first movement, Maestoso largamente, presents two distinct musical ideas, while the second movement, a Scherzo con variazioni, consists of eight variations on a lively theme. The third movement, a lyrical Romanza, focuses on the cello's expressive qualities, and the finale, Allegro non troppo grazioso, concludes the work with a graceful and playful dialogue between the instruments.

Despite Saint-Saëns's efforts to promote the sonata and its positive reception among critics and performers, it did not achieve the same level of popularity as his first cello sonata during his lifetime.
