The year of 1706 had dawned before Bach turned reluctantly toward Arnstadt once more. He took occasion to make a few side trips on the way, stopping over at Hamburg and Lüneburg to greet old associates and friends. By the end of January he was back in the organ loft of St. Boniface. His return was not exactly a love feast. The congregation and Consistory were looking for a capable, mild-mannered organist, not a disquieting virtuoso. But in a relatively short period Bach had become just that. He was plainly above the musical heads of the townsfolk. There were murmurings of discontent which were duly brought to his attention. He paid not the slightest heed, till finally the Consistory proceeded to lay down the law. The authorities had quite a number of bones to pick with their refractory young genius. They had given him a leave of one month, not of four. He answered that he imagined his substitute was competent to fill his shoes for the extra time. Far from being placated the worthy elders then reproached him for accompanying the church hymns with all sorts of brilliant and audacious improvisations, full of unexpected harmonies and variations which left the congregation groping blindly for the melody. When people had remonstrated that his preludes, interludes and postludes were too long, he had gone to the other extreme and made them too short. And there was worse to come: when he was practicing at St. Boniface, people had been scandalized to overhear the voice of a “strange maiden,” singing to his accompaniment! Such things could not be tolerated any more than an organist whose relations with his choir were so bad that he refused to rehearse it. So he could take his choice—either do what the Consistory required or else....
Bach did neither one thing nor the other but lived for a while in an uneasy state of compromise. He was not in the least minded to renounce the company of the “strange maiden”—probably the same one he was seeing home the night Geyersbach and his rowdies attacked him. She was none other than his cousin, Maria Barbara, and daughter of Bach’s uncle Michael from nearby Gehren. It was not long before he proposed to the musically talented girl and was accepted—the first case of intermarriage between two of the Bach stock. In the fullness of time she became the mother of two of Bach’s most gifted sons.
