This volume presents, for the first time, all those arias from the oratorios, Passions, Masses and sacred and secular cantatas of Johann Sebastian Bach that contain obbligato parts for one or two flutes. The musical text has been adopted from the 'Urtext' of the New Bach Edition. Music and words are inseparable in Bach's works. Therefore, as an aid to the interpretation of these flute solos, our richly annotated collection offers not only flute part but also the complete vocal part for each movement. In this way, the edition not only represents a novel form of orchestral studies, it also opens up an important area of the flute repertoire.
