For several years, Karl was obliged to lead the same shifting, nomadic sort of life, never stopping long, but dragged hither and thither in obedience to his father's vagaries and necessities, but always studying under the best masters who could be obtained. While under Kalcher, several masses, sonatas, trios, and an opera, "Die Macht der Liebe und des Weins" ("The Might of Love and Wine"), were written. Another opera, "Das Waldmaed-chen" ("The Forest Maiden"), was composed and produced when he was fourteen; and two years later in Salzburg he composed "Peter Schmoll und seine Nachbarn," an operetta, which exacted warm praise from Michael Haydn. At the age of seventeen he became the pupil of the great teacher Abbe Vogler, under whose charge also Meyerbeer was then studying. Our young composer worked with great assiduity under the able instruction of Vogier, who was of vast service in bringing the chaos of his previous contradictory teachings into order and light. All these musical _Wanderjahre_, however trying, had steeled Karl Maria into a stern self-reliance, and he found in his skill as an engraver the means to remedy his father's wastefulness and folly. II. A curious episode in Weber's life was his connection with the royal family of Wurtemberg, where he found a dissolute, poverty-stricken court, and a whimsical, arrogant, half-crazy king. Here he remained four years in a half-official musical position, his nominal duty being that of secretary to the king's brother, Prince Ludwig. This part of his career was almost a sheer waste, full of dreary and irritating experiences, which Weber afterward spoke of with disgust and regret. His spirit revolted from the capricious tyranny which he was obliged to undergo, but circumstances seem to have coerced him into a protracted endurance of the place. His letters tell us how bitterly he detested the king and his dull, pompous court, though Prince Ludwig in a way seemed to have been attached to his secretary. One of his biographers says: "Weber hated the king, of whose wild caprice and vices he witnessed daily scenes, before whose palace-gates he was obliged to slink bareheaded, and who treated him with unmerited ignominy. Sceptre and crown had never been imposing objects in his eyes, unless worn by a worthy man; and consequently he was wont, in the thoughtless levity of youth, to forget the dangers he ran, and to answer the king with a freedom of tone which the autocrat was all unused to hear. In turn he was detested by the monarch. As negotiator for the spendthrift Prince Ludwig, he was already obnoxious enough; and it sometimes happened that, by way of variety to the customary torrent of invective, the king, after keeping the secretary for hours in his antechamber, would receive him only to turn him rudely out of the room, without hearing a word he had to say."
