onstanze Mozart traveled to Baden, a spa just outside Vienna, in the late Spring of 1791, the better to weather several days of her sixth pregnancy. She would ultimately give birth to Franz Xaver Wolfgang in July. Her husband, Wolfgang Amadè, made several trips to visit her there, and on one occasion found the opportunity to compose a little motet for choir and strings as a gift to the local choirmaster Anton Stoll, with whom he had become friendly.		Written to celebrate the feast of Corpus Christi, which H.C. Robbins Landon reminds us was of particular importance in Austria, Ave Verum Corpus was first performed at the parish church in Baden on Corpus Christi day in 1791. Mozart’s autograph is dated 17 June 1791.
