I'm working on an analysis of Movement II from Beethoven's Pathétique Sonata.
In the measures shown in the image, I am trying to analyze the nonchord tones that occur in the chromatic descending lines.
For example, the first chord shown is B♭7. In that descending line, the first C can probably be labeled as an anticipation. But what about the second C? If that was a suspension, would it be labeled as something like 9-♮8? Is it better to simplify it and call each group of two of the same notes a passing tone?
Any insights would be appreciated. Thank you!
