Vier Arietten und ein Duett modulation analysis - Kaylin Templeton

 Beethoven’s Vier Arietten und ein Duett starts off in A major. This is the main key as it keeps coming back. The first time it modulates is in measure 6, which modulates to E major. It only lasts a few bars, as A major is prominent in measure 9. In measure 13, it modulates to C major. Measure 21 modulates to E major, then back to A major by measure 25. Measure 29 modulates to G major, and then back to A major in measure 33, and stays in that key until the end of the piece. The duet uses E major as A major’s closely related key, but G major and C major are not closely related to A major.
