18 Characteristic Studies, Op. 109 was composed as a sequel to the 25 Progressive Pieces, Op. 100 and dedicated to Stephen Heller. These Romantic-era pieces fit into an upper-intermediate level of musical and technical development. Fine material to study prior to the preludes and waltzes of Chopin (Jane Magrath).
