A mutation stop whose English name would be fortieth. Supporting the 8' harmonic series, it speaks at 1/6' pitch. At that pitch it would have to break back after two octaves. It is listed only by Wedgwood, who says: “Mixture ranks of high pitch are sometimes found on Italian organs, drawing separately.”
Quadragesima, Organo Grosso; Chiesa di San Tommaso Apostolo, Caselfranco di Sopra, Italy; unknown 1824.
