There is a reason that I placed the plural "s" in parentheses for my question. I noticed that only the blessings preceding the haftarah have trope notes. Since this is not part of the haftarah itself, why does the blessing need any trope?
2nd question - It looks like the wording is actually two blessings as the common introductory phrase "Baruch ata Hashem" appears twice. However the trope has an etnachta at the end of the first blessing rather than a sof pasuk. Thus, it seems that these two blessings are combined as one "long one" as if it were a single pasuk. Is it one or two brachot?
3rd question - Why is there no trope for the blessings AFTER the Haftarah?
