Saint-Georges's first compositions, Op. I, were a set of six string quartets, among the first in France, published by famed French publisher, composer, and teacher Antoine Bailleux. They were inspired by Haydn's earliest quartets, brought from Vienna by Baron Bagge. Saint-Georges wrote two more sets of six string quartets, three forte-piano and violin sonatas, a sonata for harp and flute, and six violin duets. The music for three other known compositions were lost: a cello sonata, performed in Lille in 1792, a concerto for clarinet, and one for bassoon.
