I think the question title pretty much states everything.
I'm seeking a live shiur (lecture) that focuses on iyun tefilla - understanding the prayers. Preferably, I would like the class to discuss things from a somewhat "introductory" level focusing on the history of prayer, overall, how it evolved, how and why it eventually became congregational, and when / why it moved to a Bet Knesset. I'd also like it to focus on a selected prayer service (e.g. Shacharit weekday, etc.)
I have been reading Steinzaltz intro book on prayer and it is quite good. But, I'd prefer a live discussion either in person or online (Skype, etc.) I haven't been able to locate either. Does anyone have any suggestions?
