During his lifetime, composer, piano manufacturer, and publisher Ignaz Pleyel bestowed upon the world of music an almost unimaginable number of published compositions, some of them in multiple arrangements, too. Of those, what has remained in the repertoire today are primarily works for small chamber ensembles. Several violin duos, for instance, have maintained their place among enthusiasts and students, among them in particular the Little Duos in Increasing Difficulty, which appeared in print in 1806 at the urging of several teachers (according to the title page!). Now for the first time, G. Henle Publishers presents these light performance pieces in an Urtext edition - both in full score and as two individual parts to optimize use for any occasion.
