Grand Bourdon English

In addition to being a synonym for Contra Bourdon, the name Grand Bourdon has been used for a large pedal mixture, supporting the 32' harmonic series. It is, essentially, a form of Acoustic Bass. According to Locher, the earliest known example was made by Walcker of Ludwigsburg for Ulm, Münster, Germany in 1856, consisting of five Diapason ranks at 16', 10-2/3', 8', 6-2/5', and 4'. In practice, some or all of the ranks of this mixture may be borrowed from other stops.
