Hexachordum Apollinis (the title roughly translates to "Six Strings of Apollo") was published in 1699 in Nuremberg by Johann Christoph Weigel, a publisher who had worked with Pachelbel before.
The aria Sebaldina is the sixth in the set. Sebaldina almost certainly refers to St. Sebaldus Church in Nuremberg, where Pachelbel was working at the time. Scholar Willi Apel once suggested that the aria's melody may have been a traditional tune associated somehow with the church, and not an original Pachelbel composition. (Wikipedia)
