The theory seems pretty accurate. However, I do disagree with a number of the assertions you made, as well as the strong language you used to describe Beethoven's emotions.Is the Pathetique really one of the most challenging sonatas? Perhaps out of his first ten or so, yes. But if you look at the later ones (Tempest, Appassionata, Hammerklavier, Sonatas Opus 109, 110, and 111, to name a few) are deeper, more passionate, and even more difficult (not that the Pathetique isn't hard ... ). So it might be overkill to call it one of the most difficult.One thing that I think makes Beethoven uniquely difficult to interpret, though, is that his music is never based out of just one emotion or one situation. Yes, I think the Pathetique is largely affected by his fear of hearing loss. I think you do a great job explaining how the opening sets the mood for the rest of the piece, and especially how his use of the German sixths provides false, temporary resolutions, thank you!Here's how I think of the Pathetique (be warned, this is my own opinion!): At this time in his life, he is just starting to experience hearing loss. His fear is very well communicated in the first movement, which, to date, may have been one of the most passionate pieces of music ever written. It was revolutionary in its scope and intensity. However, you also need to consider the entire sonata: The second movement is also full of pain, but this pain is far deeper, though also less visible. His music he still has, but his love he has lost. Some people try to separate Beethoven's romances from his music, but I think that is a great mistake. The second movement of the Pathetique is a love song, but one of unrequited love, a premonition of the passionate nocturnes of Chopin. The third movement is bittersweet humor, biting sarcasm--masked rage, even. Full of twists and outbursts, I think it's full of a resolution to keep going, to forge ahead into the unknown, even with everything else he's gone through. Overall, I believe the Pathetique sonata, as a whole, is Beethoven taking stock of his life, and becoming "a philosopher at the age of 28."This is my own opinion--if you feel differently, by all means feel that way. I do agree that his deafness was encroaching, but at this time in his life, it was still only very slight, more a hint of what was to come that what already had happened. The strong adjectives you used (innocent pleading, hopelessness in Beethoven's heart, anguish, sadness, etc., etc.) may well apply to the Pathetique sonata, but not to as great an extant as you seem to be using them--if you were to apply these to the Appassionata, perhaps it would be more believable.Is this helpful? BTW, it's written like an essay for a music class. If it is, good luck!
