by Klais in 1978. The instrument contains over 60 organ stops in four manuals and pedals. The tracker action is mechanical, while the register tracking is electrical. Choirs Choirs dedicated to singing services at the cathedral are the Limburger Domsingknaben, the Mädchenkantorei and the Domchor. Bells The cathedral's peal consists of nine bells. Seven of them form the main peal and are located in the south tower. Of these, the largest and smallest bell are the remnants of the peal cast in 1906 by the bellfounders of Gescher (a0–c1–d1–e1–g1–a1); they were able to be saved from destruction during the Second World War. In 1949 the other five bells (2–6) were added, which were designed to match the old bells in tone and theme. Only bell number 5 "Konrad Kurzbold" is newly arranged and added to the tone sequence. These seven bells are rung together for Christmas, Epiphany, the Gloria on Maundy Thursday and Easter Vigil, Pentecost, the Feast of St George, the anniversary of the church's consecration and consecration services. Two old bells hang in the north tower. The larger, called Sterm ("Stormbell") is a sugarloaf bell with neither symbol nor inscription, whose style dates it to 1200–1250. The smaller Uhrglocke ("hour bell") from the year 1447 originally hung in the uppermost window of the south tower. Since 1986 the two bells have been active once more. The Uhrglocke was made into a baptismal bell and is rung during every baptismal service. In addition, it is part of a special peal at Christmas time and for First Communion. Sterm is rung at Easter masses during Holy Week and for Lauds on Maundy Thursday. The full peal (Tutti) of all nine bells rings before and after the Pontifical High Mass on Easter Sunday. Concerts The cathedral is used for concerts, such as the premiere of the oratorio Laudato si' on 6 November in 2016, composed by Peter Reulein on a libretto by Helmut Schlegel on a commission from the Diocese of Limburg.
