Barenreiter Urtext BA7852 - Robert Schumann Liederkreis by H. Heine Op.24 for voice and piano. From Heinrich Heine‘s Buch der Lieder, Dedicated to Mademoiselle Pauline García. After a long time spent writing only for piano, Schumann produced a true outburst of lieder, inspired by the poetry of Heinrich Heine: “What a blessing it is, to write for the voice!” Schumann wrote to his beloved Clara. It is as though a knot was untied while he was writing the Heine-Liederkreis, op. 24.
