E. E. (Ernest Edward) Kellett translation
This expression, “deceptive” cadence, is a translation of cadenza d’inganno, one of the several cadences or closes which had names given to them by the old theorists. The “inganno” cadence was something like the “interrupted” cadence, but was supposed to lead into another key, hence the “deception.”
