Cambiata
Cambiata, or nota cambiata (Italian for changed note), has a number of different and related meanings in music. Generally it refers to a pattern in a homophonic or polyphonic (and usually contrapuntal) setting of a melody where a note is skipped from (typically by an interval of a third) in one direction (either going up or down in pitch) followed by the note skipped to, and then by motion in the opposite direction, and where either the note skipped from is distinguished as a dissonance or the note skipped to is distinguished as a non-harmonic or non-chordal tone. With regards to music pedagogical activities and species counterpoint, it refers to a more specific set of patterns.
The cambiata is also called changing note in English, though the literal meaning of the Italian is changed note.[1] It is not to be confused with changing tones, which resolve to the original note. The terminology used in other languages (G. Wechselnote, Fr. note de rechange) all of which relate to the concepts of "change" or "exchange".
