At the beginning of his career Bach was thrown upon his inexperience. His earliest libretti, consequently, are tentative and transitory in their construction. His first Cantata was written at Arnstadt for the Easter Festival of 1704.(358) The core of the libretto is a seven-stanzaed Easter song by an unknown poet, eked out by two passages of Scripture, a Excitativo, Aria, and a verse of a congregational hymn. The Aria and Recitativo are the only original numbers of the libretto, and there is little doubt that Bach wrote them himself.(359) But the whole libretto is stamped by his personality, and reveals the inveterate subjectivity of his religion. For, disregarding the general message of the Festival, the libretto opens on the soul’s personal longing for immortality and closes on its song of victory over death. In construction it is archaic, a survival of traditions acquired from central and northern Germany through Bach’s earlier residence at Lüneburg and intercourse with Hamburg.(360) Three years passed before Bach produced his next extant Cantata. In the interval, on 29th June 1707, he resigned his Arnstadt appointment to become organist of the Church of St. Blasius at Mühlhausen.(361) Here, within the space of ten months, he produced three Cantatas, the uniform character of whose libretti points to local and transitory influence upon the composer. The first of them,(362) written in August 1707, is a setting of Psalm 130, with the addition of two hymn-stanzas. The second(363) was performed on 4th February 1708, at the inauguration of the Mühlhausen Town Council, and consists of Old Testament passages, a verse of a hymn, and three original stanzas. The third,(364) a wedding Cantata, was performed at Dornheim, near Arnstadt, on 5th June 1708, at the marriage of Pastor Johann Lorenz Stauber to Frau Bach’s aunt, and is set to four verses of Psalm 115.
