Terzschritt
In music theory, Terzschritt (German: third step) is the progression from one major chord to another major chord, or a minor chord to another minor chord by major third root movement.[1] Additionally, and more specifically, it is a dualistic major third relationship, in which the ascending progression from a major tonic triad to major mediant triad is equivalent to the descending one between a major tonic triad and a flat subdominant minor triad. The major chord on the mediant is itself the Terzklang (De: third chord).
"'Where is the E major chord in C major?'...a Terzschritt from the tonic....'What is the E major triad in C major?'...a Terzklang....'How does the E major triad make sense in C major?'...it functions either as III+...or as [D](SP)."[2] The subdominant parallel (Sp) of the dominant ([D]), G, is E ([D](Sp)).
