Falling in love with someone else’s spouse can result in divorce, emotional turmoil, or (in the case of composers) some very Romantic music.

Take the case of Brahms, who for most of his adult life carried a torch for Mrs. Clara Schumann, the wife of his friend and mentor, Robert Schumann. Brahms’ Piano Quartet No. 3 was a work he began around 1854-5, an especially turbulent period in his relationship with the Schumanns. Twenty years later, when it was finally finished, Brahms wrote to his publisher: “On the cover you must have a picture, namely a head with a pistol to it. I’ll send you my photograph for the purpose, and since you seem to like color printing, you can use blue coat, yellow breeches, and top-boots.”

That garb was favored by Young Werther, the Romantic hero in a novel by Goethe, who commits suicide after falling in love with a married woman.

Coincidentally, in the audience for the Viennese premiere of Brahms’s Quartet on today’s date in 1875, were Richard and Cosima Wagner. Cosima had run off with Wagner when she was still married to the famous conductor Hans von Bulow, but her diary entry for November 18th suggests she didn’t find anything Romantic in Brahms or his music.

She writes: “In the evening a soiree with the Hellmesberger Quartet, I make the acquaintance of Herr Brahms, who plays a piano quartet of his own making. A red-faced, crude-looking man, his music dry and stilted.”
