Jason Overall, president of the American firm of Goulding & Wood, describes this stop as follows: We have recently begun building a new set of pipes. We call this new stop "Cantus Flute," as it is designed to play cantus melodies in the pedal. It is a 4' Open Wood Flute, useful for Baroque chorales with alto melodies in pedal, but we were more thinking of flute melodies such as in the 4th movement of the Widor V or the variation in the Durufl� Veni Creator. Scale is 2.25" x 2.58" (inside dimension), inverted mouths, wood pipes 1-32, tuning flaps on all pipes.
