The Places - the tour visits four notable baroque churches in Bavaria, the Monastic Church of the Assumption at Rohr, the Benedictine Abbey Church of Ottobeuren, the Alte Kapelle in Regensburg and the Monastic Church of St George and St Martin at Weltenburg, near Kelheim. The Music - Music for the tour is by Johann Sebastian Bach and is taken from the works Bach wrote for the organ. He had been familiar with the instrument from childhood, and apart from a short period from 1717 to 1723 as Court Kapellmeister to Prince Leopold of Anhalt-Cothen, remained a respected performer on the instrument, a composer of organ music and an expert on the construction of the instrument.
