We begin with the _Midsummer Night's Dream_ Overture, in which the lad of sixteen sprang into fame a masterly composer. Well had he read his Shakespeare,--the bard who fascinates the heart and soul of childhood before any child can be supposed to understand him! What a felicitous reproduction of the fairy element in tones! The perfect fairy overture, it is still heard with delight by old and young, and ever will be, it is so fresh, spontaneous, genuine, such an honest emanation from the enthusiastic heart and imagination of the boy composer. The other movements now commonly sung and played with the drama were the afterthought of Mendelssohn's riper period, when he was thirty-four years old. Schumann says: "His music is a meditation on the play, _a bridge between Bottom and Oberon_, without which the passage into Fairy Land is almost impossible." The same fairy vein, the same dainty elfin motives, or some of the same family, are met in many of the earlier and later works of Felix. That vein haunted him; it was a lucky string to play upon. Ballad movements, Canzonettas, _Volkslieder_, and the like quaint melodies, abound as well. The Overture is numbered Op. 21. Sketched or completed about the same time were the Octet, Op. 20, the first set of the Songs without Words, and the first Quintet, in A; all works of ripe and finished art of a clearly asserted, pronounced individuality. These mark the culmination of his youthful period. His early piano efforts are in many forms, mostly with strings. He wrote three Sonatas for piano solo, but soon ceased to cultivate that field (in face of Beethoven?). But he had already opened a new and original field for himself, albeit a less ambitious one, in the Songs without Words, a field to which he returned _con amore_ from time to time until late in his short life. One is tempted to describe some of these choice little tone-poems, were there room; at least the three Gondola Songs. Had he been reading Shelley: "My soul is an enchanted boat, Which like a sleeping swan doth float Upon the silver waves of thy sweet singing."
