effect as "to assimilate the dynamic trajectory of 'external form' to the 'logical' unfolding of the story of the theme". Richard Taruskin wrote that, although Mendelssohn produced works of extraordinary mastery at a very early age, he never outgrew his precocious youthful style. [...] He remained stylistically conservative [...] feeling no need to attract attention with a display of "revolutionary" novelty. Throughout his short career he remained comfortably faithful to the musical status quo – that is, the "classical" forms, as they were already thought of by his time. His version of romanticism, already evident in his earliest works, consisted in musical "pictorialism" of a fairly conventional, objective nature (though exquisitely wrought). Early works The young Mendelssohn was greatly influenced in his childhood by the music of both J. S. Bach and C. P. E. Bach, and of Beethoven, Joseph Haydn and Mozart; traces of these composers can be seen in the 13 early string symphonies. These were written from 1821 to 1823, when he was between the ages of 12 and 14, principally for performance in the Mendelssohn household, and not published or publicly performed until long after his death. His first published works were his three piano quartets (1822–1825; Op. 1 in C minor, Op. 2 in F minor and Op. 3 in B minor); but his capacities are especially revealed in a group of works of his early maturity: the String Octet (1825), the Overture A Midsummer Night's Dream (1826), which in its finished form also owes much to the influence of Adolf Bernhard Marx, at the time a close friend of Mendelssohn, and the two early string quartets: Op. 12 (1829) and Op. 13 (1827), which both show a remarkable grasp of the techniques and ideas of Beethoven's last quartets that Mendelssohn had been closely studying. These four works show an intuitive command of form, harmony, counterpoint, colour, and compositional technique, which in the opinion of R. Larry Todd justifies claims frequently made that Mendelssohn's precocity exceeded even that of Mozart in its intellectual grasp. A 2009 survey by the BBC of 16 music critics opined that Mendelssohn was the greatest composing prodigy in the history of Western classical music. Symphonies Mendelssohn's mature symphonies are numbered approximately in the order of publication, rather than the order in which they were composed. The order of composition is: 1, 5, 4, 2, 3.
