Understanding music simply means not being irritated or puzzled by it.

Here, in the last pages of the "Abegg" Variations, Schumann plays the motto theme A-B-E-G-G (B in German notation is the English Bb) not by sounding the last four notes but by taking them away, one by one, from, the chord of Bb-E-G. This is the first time in history that a melody is signified not by the attack but by the release of a series of notes. The motto, however, ends with a repeated final G. If the motto is played by releasing each successive note, we are faced with a paradox: when the G is released once on the piano, it is no longer there to be released again-the motto is not only unplayable as conceived but unimaginable. Schumann signifies as much by another paradox: he adds accents to the sustained notes.

Mendelssohn was the greatest child prodigy the history of Western music has ever known. Not even Mozart or Chopin before the age of nineteen could equal the mastery that Mendelssohn already possessed when he was only sixteen. Most astonishing is the nature of Mendelssohn's precocious talent: not only a gift for lyrical melodic lines and delicate, transparent textures, but, above all, a control of large-scale structure unsurpassed by any composer of his generation.
