Randhartinger, a friend of Franz Schubert, gave her an autographed copy of Schubert's Erlkönig, inscribing it "To the celebrated artist, Clara Wieck." Chopin described her playing to Franz Liszt, who came to hear one of Wieck's concerts and subsequently praised her extravagantly in a letter that was published in the Parisian Revue et Gazette Musicale and later, in translation, in the Leipzig journal Neue Zeitschrift für Musik. On 15 March, she was named a Königliche und Kaiserliche Österreichische Kammer-virtuosin ("Royal and Imperial Austrian Chamber Virtuoso"), Austria's highest musical honor. An anonymous music critic, describing her Vienna recitals, said: "The appearance of this artist can be regarded as epoch-making...

From then on, the couple maintained a joint musical and personal diary of their life together.

In March 1854, Brahms, Joachim, Albert Dietrich, and Julius Otto Grimm spent time with Clara Schumann, playing music for her and with her to divert her mind from the tragedy. Brahms composed some private piano pieces for her to console her: four piano pieces and a set of variations on a theme by Robert Schumann that she had also written variations on a year earlier, as her Op. 20. The music by Brahms was not intended to be published, but for her alone. Brahms later thought to publish them anonymously, but eventually they were issued as his four Ballades, Op. 10, and Variations on a Theme by Robert Schumann, Op. 9. Brahms dedicated the variations to both Schumanns, hoping that Robert would be
