New German School
His operas, his cantatas, and his instrumental music underline this. Even if his "absolute" music pays homage to one of the great string quartet and successful "obligatory violin parts" to Bach's "Well-Tempered Clavier", he displays in his other works a clear tendency for program music. Weißheimer's piano pieces "Reminiscence of Gioventu" and "At Beethoven's Grave", as well as his Symphony for Schiller's "Knight Toggenburg" match the spirit of the New German School. His literary taste is evident in the texts he set to music. German minstrel poems, texts by Johann Wolfgang von Goethe, Friedrich Schiller, Körner, Heinrich Heine and others found a musical home in his songs and cantatas.
