Gaetano Callido 1778/79

State of preservation: Restored 1975-1977 by Francesco Zanin

Callido's organ is one of the few Italian organs of the 18th century with two manuals. In a peculiar manner it shows the typical opposition of a Gran'Organo based on diapasons and the Positivo containing flute stops and "Tromboncini." There is a remarkable difference in compass: the manual of the positivo ends on C,while the main organ ends "only" on F but with a 16' basis. So the organ is, in fact, a combination of a classical 12' main organ with 8' positive.
