The following morning there was a matinée musicale at the house of the same Princess of Hesse-Barchfeld. The Frankfort String Quartet, Hugo Heermann leading, had come over for the purpose. Brahms played with them his Quartet in C Minor, Op. 60, and then accompanied me in the longest, and to me the finest, of his romances from Tieck's beautiful Magellone, " Wie soll ich die Freude, die Wonne denn tragen," Op. 33, No. 6.
