I have been going back to basics with my Greek pronunciation. My rolled "r"s are getting better (slowly) and my pitch accents are getting a little better, although I still sound like an idiot. In order to help my understanding of pitch accents, I have been going back over the accentuation rules in Hansen and Quinn and doing the accent drills. Needless to say my accents are rusty, but getting better. Hopefully it will help my Greek prose composition once I go to grad school.
Robert Strassler lecture from Marathon 2500, which I missed due to an unfortunate scheduling mishap.
