Can someone please explain this?
on: April 18, 2006, 12:35:23 PM
I am using Beethovens Op.48 No.2 Sonata as an example, but i've heard this elsewhere too. Basically I am wondering what the theoretical explanation is for the notes i've circled in red. When these bars are played, the notes in red make a very nice transition indeed. I have a feeling that Beethoven didn't just choose these notes because they sound nice, but that they have a basis in music theory. If this is correct, could someone please explain the significance, thank ya ;D

C# creates a tritone with G natural to be resolved inward (applied dominant implications)
A#, same with E natural to be resolved inward (same)

Basically in the first exaple it changes the chord from an A minor chord to an A dom7.  Look at the the function of the C#.  It's the third of the A triad, switching it from minor to major.
