With many here eager to learn more about S&P melodies, I'd like to heartily recommend the following book and CD by the late hazan of Shearith Israel in New York, The Rev. Abraham Lopes Cardoso:www.amazon.com/Sephardic-Songs-Praise-Abraham-Cardoza/dp/B000GDIC38The melodies are beautiful, his renditions are beautiful, and it's really a precious resource, especially as he grew up in Amsterdam and was able to deeply absorb the traditions there as well as in the New World where he settled...and where these traditions had developed evolved yet further.
