Seventh Chords with Added Dissonance

Seventh chords with added dissonance frequently appear in sequential passages. Bach's f-minor prelude from book II of the Well-Tempered Clavier is especially rich, almost Brahmsian, in its use of sevenths and ninths. In preparation for our class on Friday, please listen to the piece again or try it at the piano and complete the introductory questions below.


Please answer the following questions about the Bach Prelude. We will study the second half on Friday. You may want to listen to the recording played in class (Andras Schiff--WTC 2, Prelude 12).

  1. What kind of cadences occur in mm. 40, 48, 55, 60, 70? Identify the type (PAC, IAC, HC, cc, DC) and key.

  2. In the following passages, indicate the length of the model (in quarter notes) and number of sequential repetitions.

    • mm. 32-36 (descending)
    • mm. 40ff (descending)
    • mm. 44ff (rising)
    • mm. 48-52 (long one)
    • mm. 62-66 (descending)

  3. How would you characterize the music in mm. 38-40, 46-48, 52ff, 66-end? (one word answer, please)
