The vocal works collected in this volume were composed for very different occasions. Several of them were tailor-made for female singers of Beethoven's acquaintance; with others he was trying his hand at Italian opera (under the guidance of none other than Antonio Salieri). In addition to core repertoire pieces such as Ah! perfido op. 65, the volume also contains unknown treasures such as No, non turbarti - Ma tu tremi, o mio tesoro?, a scene and aria which Beethoven revised several times. In this edition, based on the Beethoven Complete Edition, the last version of the aria is made available for musicians for the first time.
