Most stops are divided in Bassi and Soprani (Bass and Treble), due to the split keyboard, which is common amongst historic Italian organs.
This is confirmed by the presence of the Contrabassi 16’, made of open wooden 16’ pipes, by the composition of the 7 rank Ripieno up to Trigesimasesta and the presence of the small Regale-like stop, the Tromboncini 8’. Zenone, Boara Polesine/Veneto (40 km south of Venice) is a beautiful example of a large-sized organ of the famous Venetian organ builder Gaetano Callido.
