Franz Thaddaus Blatt - 12 Studi op. 33, by Riccardo Amore

In 1828 he published the Méthode Complète pour la Méthode Complète pour la Clarinette, focused on the 9- and 12-key clarinet and expanded to the 13-key in the later reprint of 1839. This Method, which was widespread throughout Europe, thanks to the interest of clarinetist Domenico Liverani (1805-1877), was also reprinted in Italy by the publisher Cipriani of Bologna around 1843.

These unknown Etudes pour la Clarinette Opus are also part of his didactic production 33, kept in handwritten copy at the Biblioteka Donacji Pisarzy Polskich in Warsaw (Poland) and remained unpublished to this day.
