Carlo Francesco Badini (1715-1810) worked for a long time as a librettist at London's Italian opera house. In 1791, he wrote the text to Joseph Haydn's last opera ''L'anima del filosofo, ossia Orfeo ed Euridice''. In 1796 Badini collaborated once again with Haydn, resulting in two enchanting chamber duets for soprano, tenor and piano: ''Saper vorrei se m'ami'' and ''Guarda qui che lo vedrai'', whose bucolic setting was very popular at the time. In this Henle Urtext edition, the detailed preface by the editor Marianne Helms offers information on the complex source situation and the publication of these duets.
