Dichterliebe: Dichterliebe, "A Poet's Love" (composed 1840), is the best-known song cycle of Robert Schumann (Op.  48).  The texts for the 16 songs come from the "Lyrisches Intermezzo" of Heinrich Heine, written 1822–23 and published as part of the poet's "Das Buch der Lieder".  Following the song-cycles of Franz Schubert ("Die schöne Müllerin" and "Winterreise"), those of Schumann constitute part of the central core of the genre in musical literature.

Das Dreimäderlhaus: Das Dreimäderlhaus ("House of the Three Girls"), adapted into English-language versions as Blossom Time and Lilac Time, is a Viennese pastiche operetta with music by Franz Schubert, rearranged by Hungarian Heinrich Berté (1857–1924), and a libretto by Alfred Maria Willner and Heinz Reichert.  The work gives a fictionalized account of Schubert's romantic life, and the story was adapted from the 1912 novel "Schwammerl" by Rudolf Hans Bartsch (1873–1952).  Originally the score was mostly Berté, with just one piece of Schubert's ("Ungeduld" from "Die schöne Müllerin"), but the producers required Berté to discard his score and create a pasticcio of Schubert music.

Hermann Prey: Hermann Prey (] Berlin, 11 July 1929 – Krailling, 22 July 1998) was a German lyric baritone, who was equally at home in the Lied, operatic and concert repertoires.  His American debut was in November 1952, with the Philadelphia Orchestra and Eugene Ormandy, and his American recital debut took place in 1956, at New York's Carnegie Hall.  As a Lieder singer, he was a gifted interpreter of Schubert, including his song-cycles "Die schöne Müllerin" and "Die Winterreise" and the collection of songs "Schwanengesang", but also of Robert Schumann, Richard Strauss and Gustav Mahler.  He also appeared frequently as a soloist in Bach's "Passions" and Brahms' "A German Requiem".

Winterreise: Winterreise ("Winter Journey") is a song cycle for voice and piano by Franz Schubert (D.  911, published as Op.  89 in 1828), a setting of 24 poems by Wilhelm Müller.  It is the second of Schubert's two great song cycles on Müller's poems, the earlier being "Die schöne Müllerin" (D. 795, Op. 25, 1823).  Both were originally written for tenor voice but are frequently transposed to suit other vocal ranges – the precedent being established by Schubert himself.  These two works have posed interpretative demands on listeners and performers due to their scale and structural coherence.  Although Ludwig van Beethoven's cycle "An die ferne Geliebte" ("To the Distant Beloved") had been published earlier, in 1816, Schubert's two cycles hold the foremost place in the history of the genre.
