Sentence Rhythm

[rosends]

as far as I understand it, the Artscroll siddurim use the short vertical line to indicate the stress on a word. In this case there seems to be a tension between the line under the first syllable (rendering it A-ha-va) and the trop katon (which usually is over the stressed syllable) on the vet, making it "a-ha-VA". One wonders if this indicates a different pronunciation in different contexts but I would have to check.
