[1] Named by its first publisher, Tobias Haslinger, who presumably wished to present it as Schubert's last testament, Schwanengesang differs from the earlier Die schöne Müllerin and Winterreise song-cycles by including settings of more than one poet.
Seven texts by Ludwig Rellstab (1799–1860) are followed by six by Heinrich Heine (1797–1856); inclusion of the last song, to words by Johann Gabriel Seidl (1804–1875), may or may not reflect Schubert's wishes.
On 2 October 1828, after the manuscript had been written, Schubert offered the Heine set of six songs to a Leipzig publisher by the name of Probst.
The Seidl song, "Die Taubenpost", has no connection to the rest of the cycle and was appended by Haslinger at the end to round up all of Schubert's last compositions.
While staying faithful to Schubert's original, he often changes the piano texture as a way of providing a personal commentary on the text and music.
