Johann Sebastian Bach (1685-1750) - Air from the Orchestral Suite No. 3 in D major: a fragile, quiet adagio in the arrangement for harmonium by Alexandre Guilmant (1837-1911), a French composer and organist. The harmonium, a harmonica instrument, found its way into households, churches and concert halls as a keyboard instrument at the end of the 19th and beginning of the 20th century. Well-known composers of the time dedicated their own compositions to the harmonium or arranged and transcribed well-known pieces, which contributed to the instrument's extraordinary popularity.
My personal youth memories include many hours of playing the harmonium in the Catholic St. Raphael Church in Deutschsanktmichael (RO), the home of my ancestors http://www.deutschsanktmichael.de. The large neo-Gothic village church from 1895 with a beautiful Stuflesser altar from the Val Gardena first had an organ by Janos Soukenik from Szeged (HU). In 1919 this instrument was replaced by a harmonium by R. Metzner from Leipzig-Plagwitz. The variety of the 13 stops and the long reverberation of the enormous church hall of the village church made the harmonium an excellent organ replacement.
