I use the ArtScroll sidurim (prayer books), which include a great many vertical bars between adjacent words of the three paragraphs of "Sh'ma", wherever the editors felt people may come to slur adjacent words together. Unfortunately, these vertical bars look exactly like the vertical bars used as cantillation marks. Thus, although the sidurim include cantillation marks, any p'sik (or pasek) or munach l'garmeh is lost among the plethora of vertical bars thrown in by the ArtScroll editors. Is there any such p'sik or munach l'garmeh in "Sh'ma", and, if so, where?
The only such 'real' (cantillation) vertical bar in the three paragraphs of "Sh'ma" appears before the word "echad" in the first pasuk. (It represents a p'sik.) (Source: two good-quality chumashim.)
