Haydn String Quartet Analysis

    For the piece I analyzed, Haydn, String Quartet op. 74, no. 1, ii, mm. 1-10, I only observed one modulation. The quartet began in the key of E major, and stayed in tonic throughout the first three measures. In measure 4, the predominant can be heard with the held viio7 chord, and this continues through to measure 8. In the predominant area, there is a pivot chord in measure 7 that is the I of E major and the IV of B major, and in measure 8 the piece modulates to the key of B major, continuing the IV in a different spelling. This is possible because B is a closely related key to E with it being the dominant of E major and only one sharp is added. The key of B major remains throughout the rest of the bars, with the dominant occurring in measures 9 and 10, and the final chord being the tonic. The circled notes are embellishments not meant to be notes in the chords. Something that I am not quite sure about is the presence of G and D naturals in the first chord of the B major key, the IV of the key. I am thinking this is just a stylistic choice to add even more tension to the predominant chord.
