It was a happy life the children led, amid ideal surroundings. Felix very early showed a great fondness for music, and everything was done to foster his budding talent. With his sister Fanny, to whom he was devotedly attached, he began to have short music lessons from his mother when he was only four years old. Their progress was so satisfactory, that after a while, professional musicians were engaged to teach them piano, violin and composition, as a regular part of their education. Besides these, they must study Greek, Latin, drawing and school subjects. With so much study to be done each day, it was necessary to begin work at five o'clock in the morning. But in spite of hard work all were happy, and as for Felix nothing could dampen the flow of his high spirits; he enjoyed equally work and play, giving the same earnest attention to each. Both he and Fanny were beginning to compose, and Felix's attempts at improvising upon some comical incident in their play time would call forth peals of laughter from the inseparable children.
Soon more ambitious attempts at composition were made, the aim being to write little operas. But unless they could be performed, it was useless to try and make operas. This was a serious difficulty; but Felix was deeply in earnest in whatever he undertook, and decided he must have an orchestra to try out his operatic efforts. It looked like an impossibility, but love and money can accomplish wonders. A small orchestra was duly selected from among the members of the Court band. The lad Felix was to conduct these sedate musicians, which he did modestly but without embarrassment, standing on a footstool before his men, waving the baton like a little general. Before the first performance was quite ready, Felix felt there must be some one present who could really judge of the merits of his little piece. Who would do so better than his old professor of thorough bass and composition, Carl Zelter, the director of the Berlin Singakademie. Zelter agreed to accept this delicate office, and a large number of friends were invited for the occasion.
This was only the beginning of a series of weekly musical evenings at the Mendelssohn home. Felix, with his dark curls, his shining eyes, and charming manners, was the life of anything he undertook. He often conducted his little pieces, but did not monopolize the time. Sometimes all four children took part, Fanny at the piano, Rebekka singing, Paul playing the 'cello and Felix at the desk. Old Zelter was generally present, and though averse to praising pupils, would often say a few words of encouragement at the close.
Felix was at this time but little more than twelve years old. He had within the last year composed fifty or sixty pieces, including a trio for piano and strings, containing three movements, several sonatas for the piano, some songs and a musical comedy in three scenes, for piano and voices. All these were written with the greatest care and precision, and with the date of each neatly added. He collected his pieces into volumes; and the more work he did the more neatly he wrote.
The boy Felix had a wonderful gift for making friends. One day he suddenly caught sight of Carl Maria von Weber walking along the streets of Berlin, near his home. He recognized the famous composer at once, as he had lately visited his parents. The boy's dark eyes glowed with pleasure at the recognition, and tossing back his curls, he sprang forward and threw his arms about Weber's neck, begging him to go home with him. When the astonished musician recovered himself, he presented the boy to Jules Benedict, his young friend and pupil who walked at his side, saying, "This is Felix Mendelssohn." For response Felix, with a bright look, seized the young man's hand in both his own. Weber stood by smiling at the boy's enthusiasm. Again Felix besought them to come home with him, but Weber had to attend a rehearsal. "Is it for the opera?" the boy cried excitedly.
"Yes," answered the composer.
"Does he know all about it?" asked Felix, pointing to Benedict.
"Indeed he does," answered the composer laughing, "or if he doesn't he ought to for he has been bored enough with it already." The boy's eyes flashed.
"Then you, will come with me to my home, which is quite near, will you not?" There was no refusing those appealing dark eyes. Felix again embraced Weber, and then challenged his new friend, Mr. Benedict, to race him to the door of his house. On entering he dragged the visitor upstairs to the drawing-room, exclaiming, "Mama, Mama, here is a gentleman, a pupil of Carl Weber, who knows all about the new opera, 'Der Freischütz.'"
The young musician received a warm welcome, and was not able to leave until he had played on the piano all the airs he could remember from the wonderful new opera, which Weber had come to Berlin to superintend. Benedict was so pleased with his first visit that he came again. This time he found Felix writing music and asked what it was. "I am finishing my new quartet for piano and strings," was the simple reply. To say that Benedict was surprised at such an answer from a boy of twelve hardly expresses what he felt. It was quite true he did not yet know Felix Mendelssohn. "And now," said the boy, laying down his pen, "I will play to you, to prove how grateful I am that you played to us last time." He then sat down at the piano and played correctly several melodies from "Der Freischütz," which Benedict had played on his first visit. After that they went into the garden, and Felix for the moment, became a rollicking boy, jumping fences and climbing trees like a squirrel.
