Written by François Joseph Naderman (1781-1835) Sonatinas Progressive Op. 92 consists of a series of seven small sonatas. The level of difficulty alternates between intermediate and advanced as these can be played at different speeds but necessitates some strong technique as well as some pedal changes. These Sonatinas Progressive Op. 92 are still considered as some of the most famous pieces of the Harp repertoire today. François Joseph Naderman was a classical harpist composer and teacher at the Paris Conservatoire. His vocation was developed by growing up as the son of a LuthierHarp maker. He also wrote Sonatas for Harp Harp and Cello studies and other pieces.

Sophia Giustani Dussek's opus 2 consists of two books of three sonatas each for the harp. The Sonata in c-minor appears in the first book published by Pleyel in Paris in 1796. In this edition the composer's first name was not mentioned so the sonatas were falsely ascribed to Johann Ludwig Dussek who was quite well known in Paris at this time (cf. RISM D 4605). In the Thematic index of the works of J.L. Dussek by Howard Craw opus 2 is given as a set of 4 violin sonatas. An edition of the harp sonatas published by Corri Dussek & Co. in London and Edinburgh is ascribed to Sophia Dussek (cf. RISM D 4649).The new edition of the sonata published by Schott has been correctedaccording to this failure.The edition is part of the ABRSM syllabus and Trinity syllabus 2007 (grade 7)
