He was now, by the advice of Kunisch, put under the instruction of Maucourt, the leading violinist of Brunswick. A year later the young violinist set out for Hamburg with a few letters of introduction and a determination to appear as an artist. He failed, however, to get a hearing, and his money being exhausted, he set out on foot to return to Brunswick. In his despair he determined to make a personal appeal to the Duke of Brunswick, to whom he drew up a petition and presented it when he met the nobleman, walking in his park. The Duke asked who had worded the petition. "Well, who but I myself?" answered Spohr; "I need no help for that." The Duke said: "Come to the palace tomorrow at eleven; we will then speak further about your request." Upon which the boy departed quite happy. The Duke questioned Maucourt about Spohr's ability, and when the lad called the next day told him that he was to play one of his own compositions at the next concert in the apartments of the Duchess. His performance so pleased the Duke that the nobleman promised him instruction under competent masters and appointed him chamber musician, Aug. 2, 1799. Spohr's salary was small, but it made him independent, and enabled him to take his younger brother, Ferdinand, to live with him. At first the young chamber musician heard a good deal of French music, but an operatic company from Magdeburg introduced him to Mozart's music, and he says in his autobiography, "Mozart now became for my lifetime my ideal and model." He spent whole nights studying the scores of "Don Giovanni" and "Die Zauberflöte." Now, too, he played chamber music and first learned Beethoven's quartets. Finally the Duke asked him to select a teacher among the great violinists of the day. He at once named Viotti, but he had given up music for the business of selling wine. Ferdinand Eck was the next choice, but he declined to receive pupils. Francis Eck, his younger brother, accepted the Duke's offer and Spohr was sent with him to St. Petersburg, where he had engagements to fill. They left Brunswick on April 24, 1802. Owing to Eck's engagements his instruction of Spohr was irregular, but the boy gained much instruction from constantly hearing him. The young violinist was very industrious, often practising ten hours a day, composing considerably, and painting for recreation. While on this tour he wrote his first published violin concertos, Opus 1, A minor, and Opus 2, D minor, and the "Duos Concertants" for two violins, Opus 3. In St. Petersburg he met Clementi, Field and many minor musicians, and played frequently in chamber-music rehearsals. He also wrote in 1803 for Breitkopf and Härtel, the eminent Leipsic publishers, an article on the state of music in Russia. He returned to Brunswick in the summer of that year and heard Rode for the first time. He gave a public concert which pleased the Duke and resumed his duties as a member of the orchestra.
