Autograph musical quotation from the third movement of his Piano Concerto No. 3 in G minor (composed ca. 1820, first published 1825), signed "zur freundlichen Erinnerung I. Moscheles" ("as a friendly reminder") by the Bohemian piano virtuoso and composer, dated Leipzig, 10th January 1869, a little over a year before his death there in March 1870. Seven detailed measures, titled above and inscribed "Allegro Agitato" at the left. Page with various creases, small stains and small tears to edges, almost fully backed to another semi-rigid paper, but still very good. 8.5 x 5.5 inches; 21.5 x 14 cm. 

One of the most renowned virtuoso pianists of his time, a critic in 1821 wrote, “He is one of the best players that we have ever heard. He has Clementi’s science, Cramer’s expression, and Kalkbrenner’s brilliance. His execution is amazing, but this is a quality that ought to be only valued as a mean. The merit of this performer consists in his making such a right application of his genius, and such a wise use of the mean acquired by his indefatigable industry, as show him to be a man of taste and judgment.” A teacher of Mendelssohn, Thalberg and Litolff, Moscheles was appointed professor of piano at the Leipzig Conservatory in 1846, and his reputation and skill as a teacher were important factors in the continued success of that institution.
