Read the following paragraph and extract the answer for the question: What was the name of the person whose cantatas are restricted to special occasions such as weddings and funerals? Bach is believed to have written Christ lag in Todes Banden in 1707. He was a professional organist aged 22, employed from 1703 in Arnstadt as the organist of the New Church (which replaced the burned Bonifatiuskirche, today known as the Bach Church). At age 18, he had inspected the new organ built by Johann Friedrich Wender, was invited to play one Sunday, and was hired. The organ was built on the third tier of a theatre-like church. Bach's duties as a church musician involved some responsibility for choral music, but the exact year he began composing cantatas is unknown. Christ lag in Todes Banden is one of a small group of cantatas that survive from his early years. According to the musicologist Martin Geck, many details of the score reflect "organistic practice".In Arnstadt, the Kantor (church musician) Heindorff was responsible for church music in the Upper Church (Liebfrauenkirche), and the New Church where Bach was the organist. He typically conducted music in the Upper Church and would appoint a choir prefect for vocal music in the New Church. Wolff notes that "subjecting his works to the questionable leadership of a prefect" was not what Bach would have done. Therefore, most cantatas of the period are not for Sunday occasions, but restricted to special occasions such as weddings and funerals. Christ lag in Todes Banden is the only exception, but was most likely composed not for Arnstadt but for an application to a more important post at the Divi Blasii church in Muhlhausen.
