The antiphonal division is concealed inside the St. Michael’s loft, though it can be heard inside the church interior. Inside the loft, an acoustic channel measuring 20 metres in length carries its notes up to the sound hole at the church ceiling. That was also the case with the original organ of 1912, which was destroyed in World War II. With its fascinating sound, the rebuilt and expanded antiphonal division could be heard once again at St. Michael’s at Christmas 2009. The mysterious antiphonal division is also good for another surprise: the instrument features a drum with pebbles. When activated, it sounds like pattering rain – right in the middle of St. Michael’s!
