Patreon patron, Mr. Sullivan, recently asked the following question:
“In several of your
coursesyou have also referred to the C# in the Eroica as implying a modulation to G minor. I have never understood that statement. Would you be so kind as to enlighten me about that?”
Mr. Sullivan refers to a (dissonant!) C-sharp that appears out of nowhere in measure 7 of the first movement of Beethoven’s Symphony No. 3; a dissonance that is to have huge ramifications later in the movement. I have prepared a four-minute video explanation that I hope will do the trick.
