In November 1948 Bertold Hummel composed a short sonata for piano with the movements I. Cheerful II. very slow III. moving, lively. He kept this work, which was clearly influenced by Paul Hindemith, in his personal catalogue of works until the end of the 1950s. A few months before his death, the composer added the final phrases typical of his later style (bars 4, 8, 18) to the slow middle movement and dedicated it under the title Albumblatt to his friend Bishop Paul-Werner Scheele of Würzburg on the occasion of his golden jubilee as a priest on 1 April 2002.
