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
